Overview
The DAC108S085CIMT from Texas Instruments is a full-featured, general purpose OCTAL 10-bit voltage-output digital-to-analog converter (DAC). It operates from a single +2.7V to +5.5V supply, consuming 1.95 mW at 3V and 4.85 mW at 5V. This DAC is packaged in both 16-lead WQFN and 16-lead 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. The DAC108S085CIMT is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces and offers daisy chain operation for simultaneous updates of multiple devices using a single serial interface.
