Overview
The DAC121S101CIMKX/NOPB is a full-featured, general-purpose, 12-bit voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. This device operates from a single 2.7-V to 5.5-V supply and consumes a low current of 177 µA at 3.6 V. It features an on-chip output amplifier that allows rail-to-rail output swing and supports a three-wire serial interface compatible with standard SPI™, QSPI, MICROWIRE, and DSP interfaces, operating at clock rates up to 30 MHz. The DAC121S101 is designed for low power operation and is available in small packages, making it an excellent choice for battery-operated equipment.
