Overview
The TLC5615IDGK is a 10-bit voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device features a buffered reference input with high impedance and operates from a single 5V supply. It is designed for simplicity and reliability, incorporating a power-on-reset function to ensure repeatable start-up conditions. The DAC has an output voltage range that is two times the reference input voltage and is monotonic over temperature. Digital control is achieved through a three-wire serial bus compatible with CMOS logic and industry-standard microprocessors and microcontrollers.
