Overview
The DAC121S101CIMK is a 12-bit micro power digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for low-power applications and features a wide range of capabilities that make it suitable for various uses. It operates from a single 2.7-V to 5.5-V supply, consuming just 177 µA of current at 3.6 V. The on-chip output amplifier allows for rail-to-rail output swing, and the three-wire serial interface supports clock rates up to 30 MHz, compatible with standard SPI™, QSPI, MICROWIRE, and DSP interfaces. The DAC121S101CIMK is also AEC-Q100 Grade 1 qualified, making it suitable for automotive applications.
