Overview
The DAC8565ICPWR is a 16-bit, quad-channel, ultra-low glitch, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power, high-accuracy applications and features an internal 2.5V reference with a temperature drift of 2ppm/°C. It is particularly suited for portable, battery-operated equipment due to its low power consumption and small footprint.
