Overview
The DAC104S085CIMM/NOPB, manufactured by Texas Instruments, is a 10-bit, micropower, 4-channel digital-to-analog converter (DAC) designed for general-purpose applications. This device operates from a single 2.7-V to 5.5-V supply, consuming minimal power of 1.1 mW at 3 V and 2.5 mW at 5 V. It is packaged in compact 10-pin SON and VSSOP packages, making it the smallest QUAD DAC in its class. The DAC104S085 features a 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.
