Can OP-AMPS in STM32 G4 be used as DIFFERENTIAL AMPLIFIERS?

[Sud_09]

I was going through the reference manual of STM32G4 series MCU. I saw information on using Op-Amps inside the STM32G4 as Inverting and Non-inverting amplifiers. There was no mention of them used as differential amplifiers, can they be used as differential amplifiers?

Hello @Sud_09 and welcome to the Community,

Using OPAMPs of the STM32G4 series can indeed be used as differential amplifiers and supporting both inverting and non-inverting inputs. When using the OPAMPs as differential amplifiers, consider the following: gain settings, performance parameters, and environmental factors to ensure reliable operation.

I recommend you the Application note AN5306, which provides practical examples, including examples of OPAMP configuration (inverting and Non-inverting amplifier configurations).
