Given a small positive signal, the PGA can be used to amplify the signal to increase the dynamic range of ADC sampling and comparator trip monitoring. For example, an input signal with a valid range between 0.25V to 0.75V can be amplified in 4˟ mode to produce an output signal between 1V to 3V.
The amplified output voltage is calculated as:
