Working Principles

The MAX5251BEAP+T is a digital-to-analog converter (DAC) that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide precise analog outputs. The DAC operates by accepting serial data input (DIN) and clock input (SCLK) to convert the digital information into an analog voltage at the OUT pin. The reference voltage (VREF) determines the maximum output voltage.
