Overview
The TLC5618A, produced by Texas Instruments, is a dual 12-bit voltage output digital-to-analog converter (DAC) with buffered reference inputs (high impedance). This device is designed for simplicity and efficiency, operating from a single 5V supply and featuring a power-on reset function to ensure repeatable start-up conditions. The TLC5618A is controlled via a 3-wire CMOS-compatible serial bus, supporting SPI, QSPI, and Microwire protocols. It is particularly suited for applications requiring precise analog output control in a compact, 8-pin SOIC package.
