Overview
The DAC8871SPWR is a 16-bit, single-channel, serial input, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for high accuracy and low power consumption, making it suitable for a variety of precision applications. The DAC8871 operates with a dual power supply ranging from ±13.5V to ±19.8V and features a standard high-speed SPI serial interface capable of operating up to 50 MHz. The output range is determined by the reference voltage inputs, VREFH and VREFL, allowing for both unipolar and bipolar output configurations up to ±18V.
