In the simplest application, the PGA amplifies small input signals to increase the ADC dynamic range. The PGA also provides the additional benefit of buffering input signals from the ADC sample and hold capacitor, which further reduces sampling error.
Both the filtered and unfiltered PGA output paths are available for ADC sampling. Minimum ADC acquisition windows are recommended when sampling the PGA paths.
