The working principle of the ADS1120IRVAR is based on a delta-sigma modulator. This is a type of analog-to-digital converter in which a sampled analog signal is converted into a digitally encoded signal. The input signal is first amplified and then converted into an asynchronous bit stream. The bit stream is then decoded and reconstructed into a digital representation of the input signal. By using oversampling techniques, the ADC is able to convert input signals with very high accuracy.

The ADS1120IRVAR offers a wide range of features, including adjustable output frequency, sample rate, and amplitude. In addition, it supports multiple gain settings, dynamic range selections, and single-ended or differential input configurations. Additionally, it includes a programmable reference voltage and a temperature sensor.
