Overview
The DAC088S085CISQX from Texas Instruments is a full-featured, general-purpose, OCTAL, 8-bit, voltage-output digital-to-analog converter (DAC). It operates from a single 2.7 V to 5.5 V supply and is designed for low power consumption, making it suitable for battery-operated equipment. The DAC is packaged in both 16-pin WQFN and 16-pin TSSOP packages, with the WQFN package being the smallest in its class. The device features on-chip output amplifiers that allow 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.
