Overview
The DAC082S085CIMMX/NOPB is a highly versatile and efficient 8-bit micro power dual digital-to-analog converter (DAC) manufactured by Texas Instruments. This device is designed to operate from a single power supply ranging from 2.7 V to 5.5 V, making it suitable for a wide range of applications, particularly in battery-operated equipment. The DAC features a rail-to-rail voltage output, ensuring maximum dynamic range, and includes a power-on reset circuit that sets the output to 0 V until a valid write is performed. The device is packaged in a compact 10-pin VSSOP or WSON package, making it one of the smallest in its class.
