7.3.1.2 Background Calibration

The ADC32RF72 uses internal background calibration to maintain a high AC performance over temperature. The

calibration is performed periodically and does not require any user control or input signal, and so on. During

calibration, small changes to the signal offset are observed (approximately 30LSB). This calibration can be

frozen to avoid any disturbance during measurements using SPI writes or GPIO control.
