6.23.1 Analog Input 2 x Reference Configuration
Configures the analog input 2 x reference.
AIN2x_REF

1
Analog Input Configuration
AIN2x is configured as a single-ended input, referenced to the internal ADC common-mode voltage. If both
AIN2 channels are configured as single-ended, AIN2REF/AIN3B can be used as an additional single-ended
input, referenced to the internal ADC common-mode voltage.
AIN2x is configured as a pseudo-differential input, referenced to AIN2REF/AIN3B.
6.23.2 Analog Input 1 x Reference Configuration
Configures the analog input 1 x reference.
AIN1x_REF

Analog Input Configuration
AIN1x is configured as a single-ended input, referenced to the internal ADC common-mode voltage. If both
AIN1 channels are configured as single-ended, AIN1REF/AIN3A can be used as an additional single-ended
input, referenced to the internal ADC common-mode voltage.
AIN1x is configured as a pseudo-differential input, referenced to AIN1REF/AIN3A.
