Overview
The DAC101S101 is a full-featured, general-purpose 10-bit voltage-output digital-to-analog converter (DAC) produced by Texas Instruments. It operates from a single supply voltage ranging from +2.7 V to 5.5 V and consumes just 175 µA of current at 3.6 V. The device 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 suitable for battery-operated equipment and various industrial applications.
