Overview
The DAC101S101CIMKX is a full-featured, general-purpose 10-bit voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. This DAC operates from a single supply voltage ranging from +2.7 V to 5.5 V and consumes a low current of 175 µA at 3.6 V. It features an on-chip output amplifier that allows 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 30 MHz. The DAC101S101 is designed for low power consumption and is available in small packages, making it an excellent choice for battery-operated equipment.
