Working Principles

The AD976AAN is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It operates by taking in a digital input code and generating an analog output voltage based on the input value. The resolution of 12 bits allows for a wide range of possible output values, resulting in precise analog representation.

The DAC utilizes an internal reference voltage (VREF) and a parallel interface for data transfer. The digital input code is converted into an analog voltage using a resistive ladder network and current steering techniques. The resulting analog voltage can be used as an input for various analog systems or further processing.
