Working Principles

The AD974BR is a digital-to-analog converter that operates by converting binary digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide precise control over the output levels. The input clock signal drives the conversion process, while the serial data input determines the desired output voltage level. The converted analog voltage is then available at the VOUT pin.
