Working Principles

The ADS9120IRGER is a digital-to-analog converter that converts digital signals into analog voltage or current. It utilizes a 12-bit resolution to provide high accuracy in the conversion process. The device operates by taking in digital data through the serial data input (SDATA) pin and converting it into an analog output voltage or current.

The DAC's performance is determined by the reference voltage or current provided through the REFIN pin. The SYNC input allows for synchronization with an external clock signal, ensuring precise timing control. The full-scale adjust feature (FSADJ) enables fine-tuning of the output range for calibration purposes.

Detailed Application Field Plans

The ADS9120IRGER is suitable for a wide range of applications, including but not limited to: 1. Audio equipment: Provides high-quality analog audio signals in audio amplifiers, mixers, and digital audio workstations. 2.
