Overview
The DAC8552IDGKT is a 16-bit, dual-channel, voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low power operation and features a flexible serial host interface. Each on-chip precision output amplifier allows for rail-to-rail output swing over a supply range of 2.7V to 5.5V. The DAC8552 is particularly suited for portable, battery-operated equipment and other low-power applications due to its micro-power operation and power-down capabilities.
