What are the key features of DAC8831IBDG4?
- 16-bit resolution with 0.0031% maximum linearity error enabling precise analogue control in industrial and instrumentation applications
- Bipolar output range of -2.5 V to +2.5 V from a serial SPI interface simplifying interfacing to 16-bit MCUs and DSPs
- 14-pin SOIC tube packaging with industrial temperature grade (I suffix) supporting -40 degrees C to +85 degrees C operation
What is DAC8831IBDG4 used for?
The DAC8831IBDG4 is suited for precision analogue output control in industrial process control systems, programmable voltage sources, and closed-loop servo motor drives where 16-bit resolution translates to sub-millivolt output steps from a 5 V reference. Its bipolar output range of -2.5 V to 2.5 V directly drives instrumentation amplifier inputs or actuator control circuits without an additional inverting op-amp stage. Medical equipment, automated test systems, and precision calibration instruments also leverage its low linearity error of 0.0031% to meet tight measurement accuracy requirements.

Frequently Asked Questions
What output voltage resolution does the DAC8831IBDG4 provide when used with a 5 V reference?
With a 5 V full-scale reference and 16-bit resolution, the DAC8831IBDG4 achieves a voltage step size of approximately 76.3 microvolts per LSB (5 V divided by 65,536 codes). In bipolar mode spanning -2.5 V to +2.5 V, each step is approximately 76.3 uV, enabling sub-millivolt positioning accuracy in servo and precision analogue output applications.
How does the 0.0031% linearity error specification of DAC8831IBDG4 translate to real analogue output accuracy?
A linearity error of 0.0031% relative to a 5 V full-scale output corresponds to approximately 155 microvolts maximum deviation from the ideal transfer function. This is equivalent to about 2 LSBs at 16-bit resolution and meets the accuracy requirements of 14-bit and 15-bit effective measurement systems, making the DAC suitable for precision calibration references and closed-loop control output stages.
For a programmable current source design, how should the SPI interface of DAC8831IBDG4 be connected to a 3.3 V MCU?
The DAC8831IBDG4 accepts a 16-bit serial word via a 3-wire SPI interface consisting of CS (chip select), SCLK (clock), and DIN (data). When driven from a 3.3 V MCU, the logic threshold is compatible provided the DAC's digital supply Vdd is also set to 3.3 V. SCLK can run at up to 50 MHz, so a standard SPI peripheral at 20 MHz provides ample update rate for audio-rate or control-loop DAC updates without level-shifter circuitry.
When is DAC8831IBDG4 preferred over a 12-bit DAC in a sensor calibration instrument?
In a sensor calibration instrument requiring better than 0.01% full-scale accuracy, the 16-bit DAC8831IBDG4 is the appropriate choice because its 65,536 output steps reduce quantisation error to under 0.002% compared to 0.024% for a 12-bit device with 4,096 steps. The additional 4 bits of resolution allow direct substitution of a precision reference signal without a multi-stage amplifier ladder that would introduce its own gain error and noise floor.
