(1) Total unadjusted error includes offset, full-scale, and linearity errors. See Figure 3. None of these A/Ds requires a zero or full-scale
adjust. However, if an all zero code is desired for an analog input other than 0.0V,or if a narrow full-scale span exists (for example: 0.5V
to 4.5V full-scale)the reference voltages can be adjusted to achieve this. See Figure 13.
(2) Two on-chip diodes are tied to each analog input which will forward conduct for analog input voltages one diode drop below ground or
one diode drop greater than the VCCsupply. The spec allows 100 mV forward bias of either diode. This means that as long as the analog
VIN does not exceed the supply voltage by more than 100 mV, the output code will be correct. To achieve an absolute0 VDC to 5 VDC
input voltage range will therefore require a minimum supply voltage of 4.900 VDC over temperature variations, initial tolerance and
loading.
(3) Comparator input current is a bias current into or out of the chopper stabilized comparator. The bias current varies directly with clock
frequency and has little temperature dependence (Figure 6).

Functional Description
Multiplexer: The device contains a 16-channel single-ended analog signal multiplexer. A particular input channel
is selected by using the address decoder. Table 1 shows the input states for the address line and the expansion
control line to select any channel. The address is latched into the decoder on the low-to-high transition of the
address latch enable signal.

Additional single-ended analog signals can be multiplexed to the A/D converter by disabling all the multiplexer
inputs using the expansion control. The additional external signals are connected to the comparator input and the
device ground. Additional signal conditioning (i.e., prescaling, sample and hold, instrumentation amplification,
etc.) may also be added between the analog input signal and the comparator input.
CONVERTER CHARACTERISTICS
The Converter
The heart of this single chip data acquisition system is its8-bit analog-to-digital converter. The converter is
designed to give fast, accurate, and repeatable conversions over a wide range of temperatures. The converter is
partitioned into 3 major sections: the 256R ladder network, the successive approximation register, and the
comparator. The converter's digital outputs are positive true.
The 256R ladder network approach Figure 1 was chosen over the conventional R/2R ladder because of its
inherent monotonicity, which specifies no missing digital codes. Monotonicity is particularly important in closed
loop feedback control systems. A non-monotonic relationship can cause oscillations that will be catastrophic for
the system. Additionally, the 256R network does not cause load variations on the reference voltage.
The bottom resistor and the top resistor of the ladder networking Figure 1 are not the same value as the
remainder of the network. The difference in these resistors causes the output characteristic to be symmetrical
with the zero and full-scale points of the transfer curve. The first output transition occurs when the analog signal
has reached + ½ LSB and succeeding output transitions occur every 1 LSB later up to full-scale.

Figure 4. Typical Error Curve
Timing Diagram
Figure 5.
The successive approximation register (SAR) performs 8 iterations to approximate the input voltage. For any
SAR type converter, n-iterations are required for an n-bit converter. Figure 2 shows a typical example of a 3-bit
converter. In the ADC0816,ADC0817, the approximation technique is extended to 8 bits using the 256Rnetwork.
The A/D converter's successive approximation register (SAR)is reset on the positive edge of the start conversion
(SC) pulse. The conversion is begun on the falling edge of the start conversion pulse. A conversion in process
will be interrupted by receipt of a new start conversion pulse. Continuous conversion may be accomplished by
tying the end-of-conversion(EOC) output to the SC input. If used in this mode, an external start conversion pulse
should be applied after power up. End-of-conversion will go low between 0 and 8 clock pulses after the rising
edge of start conversion.
The most important section of the A/D converter is the comparator. It is this section which is responsible for the
ultimate accuracy of the entire converter. It is also the comparator drift which has the greatest influence on the
repeatability of the device. A chopper-stabilized comparator provides the most effective method of satisfying all
the converter requirements.
The chopper-stabilized comparator converts the DC input signal into an AC signal. This signal is then fed through
a high gain AC amplifier and has the DC level restored. This technique limits the drift component of the amplifier
since the drift is a DC component which is not passed by the AC amplifier. This makes the entire A/D converter
extremely insensitive to temperature, long term drift and input offset errors.
Figure 4 shows a typical error curve for the ADC0816 as measured using the procedures outlined in AN-179.

APPLICATION INFORMATION
OPERATION
Ratiometric Conversion
The ADC0816, ADC0817 is designed as a complete Data Acquisition System (DAS) for ratiometric conversion
systems. In ratiometric systems, the physical variable being measured is expressed as a percentage of full-scale
which is not necessarily related to an absolute standard. The voltage input to the ADC0816 is expressed by the
equation
(1)
Where:
VIN = Input voltage into the ADC0816
Vfs = Full-scale voltage
VZ = Zero voltage
DX = Data point being measured
DMAX = Maximum data limit
DMIN = Minimum data limit
A good example of a ratiometric transducer is a potentiometer used as a position sensor. The position of the
wiper is directly proportional to the output voltage which is a ratio of the full-scale voltage across it. Since the
data is represented as a proportion of full-scale, reference requirements are greatly reduced, eliminating a large
source of error and cost for many applications. A major advantage of the ADC0816, ADC0817 is that the input
voltage range is equal to the supply range so the transducers can be connected directly across the supply and
their outputs connected directly into the multiplexer inputs, (Figure 9).
Ratiometric transducers such as potentiometers, strain gauges, thermistor bridges, pressure transducers, etc.,
are suitable for measuring proportional relationships; however, many types of measurements must be referred to
an absolute standard such as voltage or current. This means a system reference must be used which relates the
full-scale voltage to the standard volt. For example, if VCC = VREF = 5.12V, then the full-scale range is divided into
256 standard steps. The smallest standard step is 1 LSB which is then 20 mV.
Resistor Ladder Limitations
The voltages from the resistor ladder are compared to the selected input 8 times in a conversion. These voltages
are coupled to the comparator via an analog switch tree which is referenced to the supply. The voltages at the
top, center and bottom of the ladder must be controlled to maintain proper operation.
The top of the ladder, Ref(+), should not be more positive than the supply, and the bottom of the ladder, Ref(−),
should not be more negative than ground. The center of the ladder voltage must also be near the center of the
supply because the analog switch tree changes from N-channel switches to P-channel switches. These
limitations are automatically satisfied in ratiometric systems and can be easily met in ground referenced systems.
Figure 10 shows a ground referenced system with a separate supply and reference. In this system, the supply
must be trimmed to match the reference voltage. For instance, if a5.12V reference is used, the supply should be
adjusted to the same voltage within 0.1V.

Figure 9. Ratiometric Conversion System
The ADC0816 needs less than a milliamp of supply current so developing the supply from the reference is
readily accomplished. In Figure 11 a ground references system is shown which generates the supply from the
reference. The buffer shown can be an op amp of sufficient drive to supply the milliamp of supply current and the
desired bus drive, or if a capacitive bus is driven by the outputs a large capacitor will supply the transient supply
current as seen in Figure 12. The LM301 is overcompensated to insure stability when loaded by the 10 μF output
capacitor.
The top and bottom ladder voltages cannot exceed VCCand ground, respectively, but they can be symmetrically
less than VCC and greater than ground. The center of the ladder voltage should always be near the center of the
supply. The sensitivity of the converter can be increased, (i.e., size of the LSB steps decreased) by using a
symmetrical reference system. In Figure 13, a2.5V reference is symmetrically centered about VCC/2 since the
same current flows in identical resistors. This system with a 2.5V reference allows the LSB to be half the size of
the LSB in a 5V reference system.

Analog Comparator Inputs
The dynamic comparator input current is caused by the periodic switching of on-chip stray capacitances These
are connected alternately to the output of the resistor ladder/switch tree network and to the comparator input as
part of the operation of the chopper stabilized comparator.
The average value of the comparator input current varies directly with clock frequency and with VIN as shown in
Figure 6.
If no filter capacitors are used at the analog or comparator inputs and the signal source impedances are low, the
comparator input current should not introduce converter errors, as the transient created by the capacitance
discharge will die out before the comparator output is strobed.
If input filter capacitors are desired for noise reduction and signal conditioning they will tend to average out the
dynamic comparator input current. It will then take on the characteristics of a DC bias current whose effect can
be predicted conventionally. See AN-258 for further discussion.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
