Overview
The TLC5615IDR is a 10-bit voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for simplicity and efficiency, operating from a single 5V supply and featuring a buffered reference input with high impedance. The DAC is monotonic and has an output voltage range that is two times the reference voltage. It includes an internal power-on reset to ensure repeatable start-up conditions and is controlled via a three-wire serial bus compatible with CMOS logic and industry-standard microprocessors and microcontrollers.
