The DAC81402RHBR from Texas Instruments is a pin-compatible, dual-channel, buffered, high-voltage-output digital-to-analog converter (DAC). This 16-bit device integrates a low-drift, 2.5-V precision reference, eliminating the need for an external reference in many applications. It is specified as monotonic with high linearity, offering ±1 LSB INL.
The DAC81402RHBR supports user-selectable full-scale bipolar output voltages of ±5 V, ±10 V, and ±20 V, as well as unipolar voltages of 5 V, 10 V, 20 V, and 40 V. Each channel's output range is independently programmable. The integrated output buffers can sink or source up to ±15 mA, reducing the need for additional operational amplifiers. Reliability features include CRC error check, short-circuit protection, and a fault pin.
Communication is handled via a 4-wire SPI-compatible serial interface operating from 1.7 V to 5.5 V, supporting readback and daisy-chain operations. The device is housed in a 32-pin VQFN package measuring 5 mm x 5 mm and operates across a temperature range of -40°C to +125°C. It is suitable for applications such as servo drive control modules, analog output modules, lab and field instrumentation, data acquisition, and semiconductor testing.
