  • calibration mode: calibration of the selected transistors differential pair NMOS or PMOS. CSR CALON LL_OPAMP_GetMode
Parameters:
OPAMPxOPAMP instance
Return values:
Returnedvalue can be one of the following values:

  • LL_OPAMP_MODE_FUNCTIONAL
  • LL_OPAMP_MODE_CALIBRATION

Definition at line 343 of file stm32l4xx_ll_opamp.h.

__STATIC_INLINE uint32_t LL_OPAMP_GetPGAGain ( OPAMP_TypeDef *  OPAMPx )

Get OPAMP PGA gain.

Note:
Preliminarily, OPAMP must be set in mode PGA using function LL_OPAMP_SetFunctionalMode(). CSR PGGAIN LL_OPAMP_GetPGAGain
Parameters:
OPAMPxOPAMP instance
Return values:
Returnedvalue can be one of the following values:

  • LL_OPAMP_PGA_GAIN_2
  • LL_OPAMP_PGA_GAIN_4
  • LL_OPAMP_PGA_GAIN_8
  • LL_OPAMP_PGA_GAIN_16

Definition at line 410 of file stm32l4xx_ll_opamp.h.

CSR OPALPM LL_OPAMP_GetPowerMode

Parameters:
OPAMPxOPAMP instance
Return values:
Returnedvalue can be one of the following values:

  • LL_OPAMP_POWERMODE_NORMAL
  • LL_OPAMP_POWERMODE_LOWPOWER

Definition at line 302 of file stm32l4xx_ll_opamp.h.

__STATIC_INLINE uint32_t LL_OPAMP_GetPowerRange ( void   )

Get OPAMP power range.

Note:
