Overview
The DAC124S085CIMM/NOPB from Texas Instruments is a 12-bit, micropower, quad-channel digital-to-analog converter (DAC) designed for general-purpose applications. This device operates from a single supply voltage ranging from 2.7 V to 5.5 V and is notable for its low power consumption, consuming 1.1 mW at 3 V and 2.4 mW at 5 V. The DAC124S085 is packaged in compact 10-pin WSON and VSSOP packages, making it the smallest quad DAC in its class. It features a three-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces, operating at clock rates up to 40 MHz across the entire supply voltage range.
