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.
