Overview
The DAC081S101CIMKX/NOPB from Texas Instruments is a highly versatile and efficient 8-bit micro power digital-to-analog converter (DAC). This device is designed for low power operation, making it ideal for battery-powered instruments and other applications where power consumption is a critical factor. The DAC operates from a single supply voltage ranging from +2.7V to +5.5V and consumes only 175 µA of current at 3.6 Volts. It features a rail-to-rail voltage output and includes an on-chip output amplifier, ensuring a wide dynamic range. The device is also compatible with various serial interfaces such as SPI, QSPI, MICROWIRE, and DSP interfaces, operating at clock rates up to 30 MHz.
