The OPA2206 is the next generation of the industry-
standard OPAx277 family with the additional feature
of input overvoltage protection. The device is a
precision bipolar, e-trim operational amplifier with
super beta inputs. The device uses TI’s proprietary
trimming technology to achieve an impressive input
offset voltage of ±2 μV (typ) and an input offset
voltage drift of ±0.04 μV/°C (typ). The input
overvoltage protection activates when the input signal
exceeds the supply range and offers protection up to
40 V beyond either supply. This feature eliminates the
need for external cumbersome circuitry to prevent the
amplifier from damages.
•

•
•
Designed on a bipolar process, the OPA2206
provides a superb speed-to-power ratio of 3.6 MHz
for a mere 220 μA. The device also achieves a low
voltage noise density of only 8 nV/√Hz at 1 kHz.
Thanks to super-beta inputs, the OPA2206 has a very
low input bias current of 100 pA (typ) and a current
noise density of 110 fA/√Hz.

•
The high performance of the OPA2206 makes this
device an excellent choice for systems requiring
high precision and low power consumption, such as
high-density analog input modules in programmable
logic controllers, field and portable instrumentation
systems, and source measurement units. The
OPA2205 is a related product with the same op amp
core, without the input protection but with improved
broadband noise (7.2 nV/√Hz).

7 Parameter Measurement Information
7.1 Typical Specifications and Distributions
Designers often have questions about a typical specification of an amplifier in order to design a more robust
circuit. As a result of natural variations in process technology and manufacturing procedures, every specification
of an amplifier exhibits some amount of deviation from the ideal value, such as the input bias current of an
amplifier. These deviations often follow Gaussian (bell curve), or normal distributions. Circuit designers can
leverage this information to guardband their system, even when there is no minimum or maximum specification
in the Electrical Characteristics.

Figure 7-1. Ideal Gaussian Distribution
Figure 7-1 shows an example distribution, where µ, is the mean of the distribution, and where σ, or sigma, is the
standard deviation of a system. For a specification that exhibits this kind of distribution, approximately two-thirds
(68.26%) of all units can be expected to have a value within one standard deviation, or one sigma, of the mean
(from µ–σ to µ+σ).
Depending on the specification, values listed in the typical column of Electrical Characteristics are represented
in different ways. As a general guideline, if a specification naturally has a nonzero mean (for example, gain
bandwidth), then the typical value is equal to the mean (µ). However, if a specification naturally has a mean near
zero (for example, input bias current), then the typical value is equal to the mean plus one standard deviation (µ
+ σ) to most accurately represent the typical value.
Use this chart to calculate the approximate probability of a specification in a unit. For example, the OPA2206
typical input bias current is ±0.1 nA; therefore, 68.2% of all devices are expected to have an input bias from ±0.1
nA. At 4σ, 99.9937% of the distribution has an input bias less than ±0.28 nA, which means that 0.0063% of the
population is outside of these limits, and corresponds to approximately 1 in 15,873 units.
Units that are found to exceed any tested minimum or maximum specifications are removed from production
material. For example, the OPA2206 has a maximum input bias of ±0.4 nA at 25°C, and although this value
corresponds to approximately 6σ (~1 in 500 million units), TI removes any unit with a larger input bias from
production material.
For specifications with no value in the minimum or maximum column, consider selecting a sigma value of
sufficient guardband for your application, and design worst-case conditions using this value. This information
should only be used to estimate the performance of a device.

8 Detailed Description
8.1 Overview
The OPA2206 is the first 36-V, bipolar, e-trim operational amplifier. This device uses a package-level offset trim
to minimize the offset voltage and offset voltage drift introduced during the manufacturing process. This trim is
performed after the device is assembled to remove any offset errors introduced throughout the manufacturing
process, and trim communication is disabled afterward. The device features super beta inputs that decrease the
input bias current and input current noise. The device also features input overvoltage protection that protects the
device for input voltages up to ±40 V beyond either supply rail.

8.3 Feature Description
8.3.1 Input Overvoltage Protection
The inputs of the OPA2206 are individually protected for voltages up to ±40 V beyond either supply. For
example, a common-mode voltage anywhere between –55 V and +55 V does not cause damage when powered
from ±15-V supplies. Internal circuitry on each input provides low series impedance under normal signal
conditions thus maintaining high performance under normal operating conditions. If the input is overloaded,
the protection circuitry limits the input current to a value of approximately 4.8 mA.
During an input overvoltage condition, current flows through the input protection diodes into the power supplies,
as shown in Figure 8-1. If the power supplies are unable to sink current, then Zener diode clamps (ZD1 and
ZD2) must be placed on the power supplies to provide a current pathway to ground. During an overvoltage
condition, the input bias current of the inputs increase as shown in Figure 8-2.

8.3.2 Input Offset Trimming
The OPA2206 is the industry's first e-trim operational amplifier built on a bipolar process. The input offset
voltage of an amplifier is determined by the inherent mismatch between the input transistors. The offset can
be minimized using laser-trimming performed during the manufacturing process while the device is still in the
bare silicon form. However, when the silicon is packaged, the packaging process introduces additional offset due
to mechanic stresses. TI's new trimming processes are used to trim the offset after the packaging process is
complete to minimize both inherent and package-induced offsets. After trimming, communication is disabled to
make sure the amplifier operates properly in the final system.
A comparison between production offset values for a the industry popular, laser-trimmed OPA2277 amplifier and
the OPA2206 proprietary trim can be seen in Figure 8-3 and Figure 8-4.

8.3.3 Lower Input Bias With Super-Beta Inputs
The OPA2206 has a super-beta input transistor architecture. In a transistor, the beta value is the ratio between
the current flowing into the base and the current flowing from the collector to the emitter. A super-beta transistor
is one where the beta value has been increased from several hundred to thousands. In a bipolar amplifier, the
input bias current is the current flowing into the base of the input transistor pair, as well as a small leakage
current that flows through the ESD diodes. A super-beta input reduces the input bias current of the amplifier. In
addition, the super-beta inputs lower the input current noise that is directly related to the input bias current of the
device. A comparison between the input bias current of the OPA2277 and the OPA2206 super-beta input bias
currents can be seen in Figure 8-6 and Figure 8-7.

8.3.4 Overload Power Limiter
Figure 8-7. OPA2206 Super-Beta Input Bias Current
In many bipolar-based amplifiers, the output stage of the amplifier can draw significant (several milliamperes)
of quiescent current if the output voltage becomes clipped (meaning the output voltage becomes limited by the
negative or positive supply voltage). This condition can cause the system to enter a high-power consumption
state, and potentially cause oscillations between the power supply and signal chain. The OPA2206 has an
advanced output stage design that eliminates this problem. When the output voltage reaches the either supply
(V+ or V–), there is virtually no additional current consumption from the nominal quiescent current. This feature
helps eliminate any potential system problems when the signal chain is disrupted by a large external transient
voltage.
8.3.5 EMI Rejection
The OPA2206 uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from
sources, such as wireless communications and densely-populated boards with a mix of analog signal chain and
digital components. EMI immunity can be improved through circuit design techniques that improve the system
performance. Additional information can be found in the EMI Rejection Ratio of Operation Amplifiers application
report.
8.4 Device Functional Modes
The OPA2206 has two functional modes. The device enters normal operation with any supply between 4.5 V
(±2.25 V) and 36 V (±18 V), and an input voltage that meets the input common-mode voltage range shown in
Section 6.
If the input voltage exceeds the device specifications, the device will enter an overvoltage protection mode. In
this mode the input overvoltage protection sub-circuit will limit the voltage and current seen by the amplifier
core by adding additional impedance between the input pins and the amplifier core. Additional current that
is generated from the voltage drop across this input impedance is routed through the ESD structure of the
OPA2206, as shown in Figure 8-1.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
9.1 Application Information
The OPA2206 is a unity-gain stable operational amplifier with very low offset voltage, offset voltage drift, voltage
noise, current noise, and power consumption. The built-in overvoltage protection allows the device to protect
against signals outside of the expected range, a reverse connection, or in cases where the inputs are shorted
to a system supply. These features make this device a great choice for a variety of space-constrained and
power-constrained systems by removing the need for discrete protection such as clamping diodes.

9.2.1.1 Design Requirements
The design requirements for this system are:
•
•
•
•
•
Input signal range: ±10 V
Input signal frequency: up to 10 kHz
3rd-order Butterworth filter -3-dB frequency: 20 kHz
Output voltage: 0 V to 5 V
Input protection: up to ±52 V
9.2.1.2 Detailed Design Procedure
In this design, a ±10-V, 10-kHz bandwidth, bipolar signal is attenuated and converted to a single-ended signal
and filtered by a 3rd-order Butterworth filter to drive a single-ended analog-to-digital converter (ADC). By using
the OPA2206, the input of the signal chain is protected from overvoltages up to 40 V beyond either supply. This
signal-chain design is common for programmable logic controllers (PLCs), low-power data acquisition systems
(DAQs) and field instruments where high precision, low power and signal fault protection are needed.
The OPA2206 was selected for this application because of the high supply range, high dc precision (2-µV offset
and 0.04-µV/°C offset drift), and low power consumption (220-µA quiescent current) that minimizes thermal
dissipation requirements. Because of the internal OVP topology, the device provides better dc and ac accuracy
under normal operating conditions compared to passive external protection and results in a smaller system
solution. Be sure to connect a zener diode between each supply to ground to provide a return path for the
current that is generated during a fault condition.

The first stage of the signal chain is an attenuator and level-shifter. The input signal to this stage is bipolar ±10 V
that is attenuated to ±2.5 V, and then level-shifted so that the output is a single-ended, 0-V to 5-V signal. The
feedback and gain resistors were selected as 20 kΩ and 80 kΩ, respectively. Thus, the combined impedance
is 100 kΩ, which lowers the input current to the signal chain, and minimizes errors resulting from higher output
impedance sensors.
The second stage of the signal chain uses the second channel of the OPA2206 to create a 3rd-order Butterworth
filter with a –3-dB response of 20 kHz. For more information on filter design, refere to Texas Instrument's filter
design tool.
The output of this signal chain is shown in Figure 9-2 and the filter response is shown in Figure 9-3.

9.2.2 Discrete, Two-Op-Amp Instrumentation Amplifier
Figure 9-4 shows the OPA2206 configured as a two op amp, discrete instrumentation amplifier. This
configuration allows for a differential signal measurement, such as the signal from a load cell, with higher input
impedance to the signal chain than most monolithic instrumentation amplifiers. Additionally, the input overvoltage
protection of the OPA2206 protects the signal chain from being damaged by fault conditions where the input
signal exceeds the supply voltage of the amplifier.

9.2.3 Input Buffer and Protection for ADC Driver
Section 9.2.1.1 shows the OPA2206 configured as an input buffer for an ADC driver using the THP210. The
high dc precision and low noise of the OPA2206 make this device an excellent choice for precision signal
chain conditioning. The low input bias of the amplifier minimizes dc errors created for higher output impedance
sensors. The integrated input overvoltage protection prevents damage to the signal chain due to an input fault
condition where the signal exceeds the supply range of the OPA2206, or if the inputs are shorted to a higher
supply rail. For more information on designing a precision ADC driver,see .

10 Power Supply Recommendations
The OPA2206 operates with a supply between 4.5 V (±2.25 V) and 36 V (±18 V). Parameters that can exhibit
significant variance with regard to operating voltages are presented in Section 6.7.
11 Layout
11.1 Layout Guidelines
For best operational performance of the device, use good printed circuit board (PCB) layout practices, including:
•
Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as close
to the device as possible. A single bypass capacitor from V+ to ground is applicable for single-supply
applications. Noise can propagate into analog circuitry through the power pins of the circuit as a whole, as
well as through the individual op amp. Bypass capacitors are used to reduce the coupled noise by providing
low-impedance power sources local to the analog circuitry.
•
•
Make sure to physically separate digital and analog grounds and pay attention to the flow of the ground
current. Separate grounding for analog and digital portions of circuitry is one of the simplest and most
effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to
ground planes. A ground plane helps distribute heat and reduces EMI noise pickup.
In order to reduce parasitic coupling, run the input traces as far away from the supply or output traces as
possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicular is much better,
as opposed to in parallel with the noisy trace.
•
•
•
Place the external components as close to the device as possible. As shown in Figure 11-1, keep RF and RG
close to the inverting input to minimize parasitic capacitance.
Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce
leakage currents from nearby traces that are at different potentials.
•
•
Clean the PCB following board assembly for best performance.
Any precision integrated circuit may experience performance shifts due to moisture ingress into the plastic
package. After any aqueous PCB cleaning process, bake the PCB assembly to remove moisture introduced
into the device packaging during the cleaning process. A low-temperature, post-cleaning bake at 85°C for 30
minutes is sufficient for most circumstances.
