Overview
The DAC088S085CISQ/NOPB, produced by Texas Instruments, is a full-featured, general-purpose, OCTAL, 8-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 1.95 mW at 3 V and 4.85 mW at 5 V. It is available in 16-pin WQFN and TSSOP packages, with the WQFN package being the smallest in its class. The DAC088S085 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 across the entire supply voltage range.
