Overview
The DAC084S085CIMMX/NOPB is a highly versatile and efficient digital-to-analog converter (DAC) produced by Texas Instruments. This device is an 8-bit, quad-channel DAC that operates from a single power supply ranging from 2.7V to 5.5V. It is designed for low-power operation, consuming only 1.1 mW at 3V and 2.5 mW at 5V, making it suitable for battery-powered applications. The DAC features a rail-to-rail voltage output 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.
