HAL_StatusTypeDef HAL_OPAMP_SelfCalibrate

(

OPAMP_HandleTypeDef *

hopamp

)

Run the self calibration of one OPAMP.

Note:

Calibration is performed in the mode specified in OPAMP init structure (mode normal or low-power). To perform calibration for both modes, repeat this function twice after OPAMP init structure accordingly updated.

Calibration runs about 10 ms.

Parameters:

hopamp

handle

Return values:

Updated	offset trimming values (PMOS & NMOS), user trimming is enabled
HAL	status
