Overview
The DAC082S085CIMMX from Texas Instruments is a full-featured, general-purpose, dual 8-bit digital-to-analog converter (DAC) designed for a wide range of applications. This device operates from a single supply voltage ranging from 2.7 V to 5.5 V and is known for its low power consumption, typically 0.6 mW at 3 V and 1.6 mW at 5 V. The DAC082S085CIMMX features a rail-to-rail voltage output and is packaged in compact 10-pin VSSOP and WSON packages, making it one of the smallest dual DACs in its class. The device includes a power-on reset circuit that ensures the output voltages are set to 0 V upon power-up, and it supports simultaneous output updating and multiple power-down modes to minimize power consumption.
