DACx0004 器件配有上电复位电路,用于确保 DAC 输
出在零量程或量程中点处上电(具体取决于 POR 引脚
的状态)并保持该状态直到器件中写入有效编码为止。
这些器件的电流消耗非常低(1mA/通道),是便携
式、电池供电类设备的理想选择。这些器件还包含一种
掉电特性。该特性可将 5V 电压下的流耗降至 3µA(典
型值)。

8 Detailed Description
8.1 Overview
The DAC80004, DAC70004, and DAC60004 are quad-channel, 16-bit, voltage-output DACs with internal
reference buffers and output buffers. Each channel consists of an R-2R ladder configuration with the 4 MSBs
segmented, followed by an operational amplifier, as shown in Figure 51. The DACx0004 devices have a constant
impedance (30 kΩ typical), buffered reference input. The output of the reference buffers drives the R-2R ladders.
With the production trim process these devices have excellent dc accuracy and ac performance.

8.3 Feature Description
8.3.1 Output Amplifier
The DACx0004 output buffer amplifier is capable of generating near rail-to-rail voltages on its output, giving a
maximum output range of 0 V to REFIN. It is capable of driving a load of 5 kΩ in parallel with 2 nF to GND. The
typical slew rate of this amplifier while driving no load is 1.5 V/µs, with a full-scale settling time of 8 µs to 1 LSB
of the final value as shown in Figure 43 and Figure 44. The current consumption of the amplifier (unloaded) is 1
mA/channel (typical). The DACx0004 output amplifier also implements a short circuit current limiting circuit. The
default value of short circuit limit is 40 mA, however this can be reduced to 30 mA using dedicated bits (1 per
channel) via SPI command 1010 (see Table 2).
8.3.2 Reference Buffer
The DACx0004 requires an external reference to operate. The reference input pin has the following input range:
2.2 V to (VDD – 0.2) for 2.7 V ≤ VDD ≤ 4.5 V
2.2 V to VDD for 4.5 V ≤ VDD ≤ 5.5 V
The DACx0004 contains a dedicated reference buffer for each DAC channel. The REFIN pin drives the input of
these buffers. The integrated reference buffers offers constant impedance of 30 kΩ (typical) at the REFIN pin.
This simplifies the external reference drive circuit for the device.
8.3.3 Power-On Reset
The DACx0004 contain a power-on-reset circuit that controls the output voltage during power up. The power-on
reset is useful in applications where it is important to know the state of the output of each DAC while the device
is in the process of powering up. At power up all DAC registers are filled with power-on reset code (see Table 1).
8.3.3.1 POR Pin Feature
The DAC power-on reset code for all of the channels depends on the state of the POR pin at power up (see Pin
Configuration and Functions).
Each DAC channel remains that way until a valid load command is written to it. All device registers are reset at
power up as shown in Table 1.

8.3.3.2 Internal Power-On Reset (IPOR) Levels
When the device powers up, an IPOR circuit sets the device in default mode as shown in Table 1. The IPOR
circuit requires specific VDD levels, as indicated in Figure 52, to ensure discharging of internal capacitors and to
reset the device on power up. In order to ensure a power-on reset, VDD must be below 0.7 V for at least 1 ms.
When VDD drops below 2.4 V but remains above 0.7 V (shown as the undefined region), the device may or may
not reset under all specified temperature and power supply conditions. In this case, In this case a power-down
reset is recommended. When VDD remains above 2.4 V, a power-on reset does not occur.

8.4 Device Functional Modes
8.4.1 Serial Interface
The DACx0004 devices have a 4-wire serial interface: SYNC, SCLK, SDIN, and SDO (see Pin Configuration and
Functions). The serial interface (3-wire and 4-wire) is compatible with SPI, QSPI, and Microwire interface
standards, as well as most DSPs and it operates up to 50 MHz. See the Write Mode Stand-Alone Timing and
Write Mode Daisy-Chain Timing diagrams (see Figure 1 and Figure 2) for examples of typical write and read
sequences. The input shift register is 32 bits wide.
8.4.1.1 Stand-Alone Mode
The serial clock SCLK can be a continuous or a gated clock. The first falling edge of SYNC starts the operation
cycle. When SYNC is high, the SCLK and SDIN signals are blocked and the SDO pin (TSSOP-14 and VSON-14
packages) is in a Hi-Z state. The device internal registers are updated from the shift register on the 32nd falling
edge of SCLK.
8.4.1.1.1 SYNC Interrupt – Stand-Alone Mode
For stand-alone operation, the SYNC line stays low for at least 32 falling edges of SCLK and the addressed DAC
register updates on the 32nd SCLK falling edge. However, if SYNC is brought high before the 32nd SCLK falling
edge, it acts as an interrupt to the write sequence; the shift register resets and the write sequence is discarded.
Neither an update of the data buffer contents, DAC register contents, nor a change in the operating mode occurs
(as shown in Figure 53).

Device Functional Modes (continued)
8.4.1.1.2 Read-Back Mode
The READ command is used to start read-back operation. However, before read-back operation can be initiated,
the SDO pin must be enabled by setting the DSDO bit to '1'; this bit is disabled by default. Read-back operation
is then started by executing a READ command (R/W bit = '1', see Table 3). Bits C3 to C0 select the register to
be read. The remaining data in the command are don’t care bits. During the next SPI operation, the data
appearing on the SDO output are from the previously addressed register. For a read of a single register, a NOP
(No Operation) command (1110) can be used to clock out the data from the selected register on SDO. Multiple
registers can be read if multiple READ commands are issued (see Figure 54).

8.4.1.2 Daisy-Chain Mode
For systems that contain more than one device, the SDO pin can be used to daisy-chain multiple devices
together (see Figure 55). Daisy-chain operation can be useful in system diagnostics and in reducing the number
of serial interface lines. The daisy-chain feature can be enabled by writing a logic '1' to the DSDO bit (see
Table 3); the SDO pin is set to HIZ when the DSDO bit is set to 0.
The first falling edge of SYNC starts the operating cycle. SCLK is continuously applied to the SPI shift register
when SYNC is low. If more than 32 clock pulses are applied, the data ripples out of the shift register and appear
on the SDO line. The data bits are clocked out on the rising edge of SCLK and are valid on the falling edge. By
connecting the SDO pin of the first device to the SDI input of the next device in the chain, a multiple-device
interface is constructed (see Figure 2). Each device in the system requires 32 clock pulses. Therefore, the total
number of clock cycles must equal 32 × N, where N is the total number of DACx0004s in the chain. When the
serial transfer to all devices is complete, SYNC is taken high. This action latches the data from the SPI shift
registers to the device internal registers for each device in the daisy-chain and prevents any further data from
being clocked in. The serial clock can be a continuous or a gated clock. Note that a continuous SCLK source can
only be used if SYNC is held low for the correct number of clock cycles. For gated clock mode, a burst clock
containing the exact number of clock cycles must be used and SYNC must be taken high after the final clock in
order to latch the data.

8.4.1.2.1 SYNC Interrupt – Daisy-Chain Mode
For daisy-chain operation, the SYNC line stays low for at least 32 × N SCLK cycles, where N is the number of
DACx0004s in the daisy chain. If SYNC is brought high before a multiple 32 SCLKs, it acts as an interrupt to the
write sequence; the shift register resets and the write sequence is discarded. Neither an update of the data buffer
contents, DAC register contents, nor a change in the operating mode occurs (see Figure 56).

The SPI shift register is 32 bits wide, as shown in Table 2. The shift register command mapping is shown in
Table 3. The DACx0004 accepts DAC code in straight binary format. Note that, the DAC data is left alligned from

8.4.3 DAC Power-Down Modes
The DACx0004 use four modes of operation. These modes are accessed by setting command bits D28 – D24
and power-down register bits D09 and D08. The command bits must be set to 0100 (see Table 3). Once the
command bits are set correctly, the four different power-down modes are software programmable by setting bits
D09 and D08 in the shift register. Table 5 shows how to control the operating mode with data bits PD1 (D09),
PD0 (D08).

It is possible to write to the DAC register/buffer of the DAC channel that is powered down. When the DAC
channel is then powered up, it powers up to this new value.
The advantage of the available power-down modes is that the output impedance of the device is known while it is
in power-down mode. As described in Table 5, there are three different power-down options. VOUTX can be
connected internally to GND through a 1 kΩ resistor, a 100 kΩ resistor, or open-circuited (Hi-Z). The DAC power-
down circuitry is shown in Figure 57.

8.4.4 CLR Pin Functionality and Software CLEAR Mode
The CLR pin is an asynchronous input pin to the DAC. When activated, this falling edge sensitive pin clears the
DAC buffers and the DAC latches to zero, mid, full or user programmed code depending on the clear mode
register (see Table 6). The default setting for clear operation is clear to 0 V. The device exits clear mode on the
32nd falling edge of the next write to the device. If the CLR pin receives a falling edge signal during a write
sequence in normal operation, the clear mode is activated and changes the input and DAC registers
immediately. Additionally, all DAC registers can also be cleared via SPI command 1011. Note that the clear
mode bits determine the clear code for all the DACs upon clear operation.
8.4.4.1 DAC Clear Mode Registers
The DACx0004 implement four different clear modes. These modes are accessed by setting command bits
D28 – D24 and clear mode register bits D01 and D00. The command bits must be set to 0101 (see Table 3).
Based on the value of clear mode register (see Table 6), all of the DAC and the buffers are cleared to zero, mid,
or full-scale code, when the CLR pin sees a falling edge or after a software clear command is issued.
The user defined clear scale can be set by writing 16-/14-/12- data to 1001 to bits D28 – D24.

8.4.5 LDAC Pin Functionality
The DACx0004 devices offer both a software and hardware simultaneous update and control function. The DAC
double-buffered architecture has been designed so that new data can be entered for each DAC without
disturbing the analog outputs. Data updates can be performed either in synchronous or in asynchronous mode.
In asynchronous mode, the LDAC pin is used as an active low signal for simultaneous DAC updates. Multiple
single-channel writes can be done in order to set different channel buffers to desired values and then pulse the
LDAC pin low to simultaneously update the DAC output registers. Data buffers of all channels must be loaded
with desired data before an LDAC low pulse. After a LDAC low pulse, all DACs are simultaneously updated with
the last contents of the corresponding data buffers. If the content of a data buffer is not changed, the
corresponding DAC output remains unchanged after the LDAC pin is pulsed low.
In synchronous mode, data are updated with the falling edge of the 32nd SCLK cycle, which follows a falling
edge of SYNC. For such synchronous updates, the LDAC pin is not required, and it must be connected to GND
permanently or asserted and held low before sending commands to the device.
8.4.5.1 Software LDAC Mode Registers
Alternatively, all DAC outputs can be updated simultaneously using the built-in software function of LDAC. The
LDAC register offers additional flexibility and control by allowing the selection of which DAC channel(s) should be
updated simultaneously when the LDAC pin is being brought low. The LDAC register is loaded with a 4-bit word
(D03 and D00) using command bits D28 – D24 (see Table 3). The default value for each bit, and therefore for
each DAC channel, is zero. If the LDAC register bit is set to 1, it overrides the LDAC pin (the LDAC pin is
internally tied low for that particular DAC channel), and this DAC channel updates synchronously after the falling
edge of the 32nd SCLK cycle. However, if the LDAC register bit is set to 0, the DAC channel is controlled by the
LDAC pin.
See Table 7 for more information.

8.4.6 Software Reset Mode
The DACx0004 implements a software reset feature. The software reset function uses command bits D28 – D24
(see Table 3). Table 1 shows the reset values for different registers.

8.4.7 Output Short Circuit Limit Register
The DACx0004 output amplifier has a default short circuit limit of 40 mA. However, this limit can be reduced to
30 mA by using command 1010 on bits D28 – D24 and selecting channel(s) (D03 – D00). Please note that
DACx0004 has a dedicated bit per channel, this allows the user to set different short circuit limit for different DAC
output channels.

8.4.8 Status Register
The DACx0004 implements a read-only status register (see Table 3). This register can be read by using
command 1101 on bits D28 – D24, followed by a NOP command.
Logic ‘1’ on bit D04 indicates that the device is ready to be used. This feature is useful to check if the device is
ready to accept commands after power up.

This design requires two channels of the DACx0004 to generate a bipolar output. The design is very flexible and
allows for many different configurations. Typically, one channel is used to finely control the output, while the other
is used to offset the output. The direction of the offset depends on which channel is used as an offset. DACPOS
provides a positive offset and DACNEG has a negative offset.
9.2.2 Detailed Design Procedure
The output of each DAC can be modified via the digital interface and the gain of each output can be modified
independently by changing the external resistors. In order for the gain of each offset to be independent,
Equation 2 must be true.

The output voltage range, VOUT, is adjusted according to Equation 3. Keep in mind that Equation 3 is only true
when Equation 2 is true.

Each DAC outputs a voltage from 0 to REFIN. As an example, if DACPOS gain is 1, DACNEG gain is 2 and RFB
2 kΩ, then RPOS = 2 kΩ, RNEG = 1 kΩ and RA = 1 kΩ. With the correct digital implementation it gives the output
an effective output range of ±15 V, with discrete 16-bit steps.

9.2.3 Application Curve
Figure 59 displays two different modes of operation. Mode 1 gains the output of DACNeg by a factor of 2 and
maintains DACPOS at unity gain. Mode 2 reverses the gains of each stage to invert the system. These are just
two examples of the types of outputs that can be achieved using this configuration.

10 Power Supply Recommendations
The DACx0004 can operate within the specified supply voltage range of 2.7 V to 5.5 V. The power applied to
VDD should be well-regulated and have low-noise. Switching power supplies and DC-DC converters often have
high frequency glitches or spikes riding on the output voltage. In addition, digital components can create similar
high frequency spikes. This noise can easily couple into the DAC output voltage through various paths between
the power connections and analog output. A 1 µF to 10 µF capacitor and 0.1 µF bypass capacitor is
recommended in order to further minimize noise from the power supply. The current consumption on the VDD
pin, the short-circuit current limit, and the load current for the device are listed in the Electrical Characteristics.
The power supply must meet the aforementioned current requirements.

11 Layout
11.1 Layout Guidelines
A precision analog component requires careful layout, adequate bypassing, and clean, well-regulated power
supplies. As a general rule it is important to keep digital traces as far away from analog traces when possible.
The DACx0004 is often used in close proximity with digital logic, microcontrollers, microprocessors, and digital
signal processors. The more digital logic present in the design and the higher the switching speed, the more
difficult it is to keep digital noise from appearing at the output.
Due to the single ground pin of the DACx0004, all return currents, including digital and analog return currents for
the DAC, must flow through a single point. Ideally, GND must be connected directly to an analog ground plane.
This plane must be separate from the ground connection for the digital components until they were connected at
the power-entry point of the system.
As with the GND connection, VDD should be connected to a 5 V power-supply plane or trace that is separate
from the connection for digital logic until they are connected at the power-entry point. It is recommended to have
an additional 1 μF to 10 μF capacitor and 0.1 μF bypass capacitor. In some situations, additional bypassing may
be required, such as a 100 μF electrolytic capacitor or even a Pi filter made up of inductors and capacitors—all
designed to essentially low-pass filter the 5 V supply, removing the high-frequency noise. In general it is always a
good idea to maintain the digital signals away from analog signals.
