Overview
The TLC5618AQD is a dual 12-bit voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device features buffered reference inputs with high impedance and is designed for simplicity and efficiency. It operates from a single 5V supply and includes a power-on reset function to ensure repeatable start-up conditions. The TLC5618AQD is controlled via a 3-wire CMOS-compatible serial bus, supporting SPI, QSPI, and Microwire communication protocols. The device is particularly useful in applications requiring precise analog output control and low power consumption.
