Overview
The DAC104S085CIMMX from Texas Instruments is a full-featured, general-purpose QUAD 10-bit voltage-output digital-to-analog converter (DAC). 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, with typical power usage of 1.1 mW at 3 V and 2.5 mW at 5 V. It is packaged in 10-pin SON and VSSOP packages, making it one of the smallest QUAD DACs in its class. The DAC104S085CIMMX features a three-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces, and it supports clock rates up to 40 MHz across the entire supply voltage range.
