Overview
The TLC5615CP, produced by Texas Instruments, is a 10-bit voltage output digital-to-analog converter (DAC) designed for a variety of applications requiring precise analog output control. This device operates from a single 5V supply and features a buffered reference input with high impedance. The DAC is monotonic and has an output voltage range that is two times the reference input voltage. It includes an internal power-on reset to ensure repeatable start-up conditions and is characterized for operation from 0°C to +70°C (TLC5615C) or -40°C to +85°C (TLC5615I).
