Overview
The Texas Instruments DAC80508MRTER is a 16-bit buffered voltage-output digital-to-analog converter (DAC) designed for high-performance applications. This device is part of the DACx0508 family and is featured on the DAC80508-04EVM evaluation module. The DAC80508 offers a 2.5V, 5ppm/°C internal reference and user-selectable gain configurations, allowing for full-scale output voltages of 1.25V, 2.5V, or 5V. It operates from a single 2.7V to 5.5V supply and is verified monotonic with exceptional linearity of ±1 LSB INL.
