Overview
The DAC088S085CIMT from Texas Instruments is a full-featured, general-purpose, OCTAL, 8-bit, voltage-output digital-to-analog converter (DAC). It operates from a single supply voltage ranging from 2.7 V to 5.5 V and consumes 1.95 mW at 3 V and 4.85 mW at 5 V. This DAC is packaged in both 16-pin WQFN and 16-pin TSSOP packages, with the WQFN package being the smallest in its class. The on-chip output amplifiers enable rail-to-rail output swing, and the three-wire serial interface supports clock rates up to 40 MHz across the entire supply voltage range, compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces.
