Working Principles

The AD974ANZ is a digital-to-analog converter (DAC) that converts digital signals into analog voltages. It utilizes a 12-bit resolution to accurately represent the digital input data as a corresponding analog voltage. The conversion process is controlled by an internal clock signal, which synchronizes the conversion of each digital sample.

The DAC operates with a single +5V power supply and features an on-chip reference voltage generator, eliminating the need for an external reference voltage source. The serial interface allows easy integration with microcontrollers and digital systems, enabling seamless communication between the DAC and the controlling device.
