Overview
The DAC124S085CIMM is a full-featured, general-purpose, quad, 12-bit, voltage-output digital-to-analog converter (DAC) produced by Texas Instruments (formerly National Semiconductor). This device 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. It is packaged in 10-pin WSON and VSSOP packages, making it the smallest quad DAC in its class. The on-chip output amplifier allows for rail-to-rail output swing, and the three-wire serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces, operating at clock rates up to 40 MHz over the entire supply voltage range.
