Overview
The TLC5620CN is a quadruple 8-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for applications requiring multiple analog outputs controlled by a digital interface. The TLC5620CN operates from a single 5-V supply and features a simple three-wire serial bus interface compatible with CMOS logic and easily interfaced to microprocessors and microcontrollers. The device includes four 8-bit DACs, each with a buffered reference input and a programmable output range of either one or two times the reference voltage. It also includes a power-on reset function to ensure repeatable start-up conditions and low-power consumption for energy-efficient operation.
