3.7.1.11 PGA Integration
• No additional external pins are required for the PGA as it is part of the ADC and is
selected as a separate channel
• Each PGA connects to the differential ADC channels
• The PGA outputs differential pairs that are connected to ADC differential input
• When the PGA is used, differential input from the pins is connected to differential
input channel 2 on ADCx
