Title:
Gain and Offset Calibration of the Analog Signal Conditioning (OPAMP) Peripheral
Description:
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.
