Overview
The DAC124S085CIMM-TI, produced by Texas Instruments, is a full-featured, general-purpose, quad, 12-bit, voltage-output digital-to-analog converter (DAC). This device operates from a single 2.7-V to 5.5-V supply and is known for its low power consumption, with typical power usage of 1.1 mW at 3 V and 2.4 mW at 5 V. It is packaged in 10-pin WSON and VSSOP packages, making it one of the smallest quad DACs in its class. The DAC124S085CIMM-TI features an on-chip output amplifier that allows rail-to-rail output swing and 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.
