Working Principles

The TLC5628IDWR is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes an 8-bit resolution to provide precise control over the output voltage levels. The device operates by receiving serial data input (DIN) and clock input (SCLK) to determine the desired analog output voltage. The chip select input (CS) enables the device, while the clear input (CLR) resets the output to zero. The load DAC input (LDAC) synchronizes the update of analog outputs.
