Overview
The DAC60508ZRTER from Texas Instruments is a part of the DACx0508 family, which includes low-power, eight-channel, buffered voltage-output digital-to-analog converters (DACs) with 12-bit resolution. This device is designed to provide high precision and flexibility, making it suitable for a variety of applications. It features an integrated 2.5 V precision internal reference, eliminating the need for an external precision reference in most cases. The DAC60508 operates from a single 2.7 V to 5.5 V supply and is specified monotonic with high linearity of ±1 LSB INL.
