Gain and Offset Calibration of the Analog Signal Conditioning (OPAMP) Peripheral
This application note describes how to calibrate the gain and offset of the Analog Signal Conditioning (OPAMP) peripheral when configured as a Programmable Gain Amplifier (PGA). The microcontroller's (MCU's) internal digital-to-analog converter (DAC) and analog-to-digital converter (ADC) are used to perform the calibration procedure. No external components are required.
