Overview
The DAC124S085 is a full-featured, general-purpose, quad, 12-bit, voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. It operates from a single 2.7-V to 5.5-V supply and is known for its low power consumption, consuming 1.1 mW at 3 V and 2.4 mW at 5 V. The device is packaged in 10-pin WSON and VSSOP packages, making it one of the smallest quad DACs in its class.
