Overview
The DAC8812ICPWR is a dual-channel, 16-bit digital-to-analog converter (DAC) designed by Texas Instruments. This device operates from a single 2.7-V to 5.5-V supply and is optimized for high-precision signal generation and low power consumption. It features a current-output architecture, making it suitable for various industrial and precision applications. The DAC8812ICPWR includes an internal feedback resistor for temperature tracking and an external I-to-V precision amplifier for accurate output. It also supports a high-speed, 3-wire SPI-compatible interface for serial data input and a common level-sensitive load DAC strobe for simultaneous update of all DAC outputs.
