Working Principles

The ADS9120IRGET is a digital-to-analog converter (DAC) that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide accurate voltage outputs. The device operates by taking in a digital input signal through the serial data input pin (DIN) and converting it into an analog voltage at the analog output pin (A). The conversion process is controlled by the serial clock input (SCLK), chip select input (CS), and synchronization input (SYNC) pins.
