STM32G4 Series "24 Operational amplifiers (OPAMP) 24.1 Introduction The devices embed six operational amplifiers with two inputs and one output each. The three I/Os can be connected to the external pins, thus enabling any type of external interconnections. The operational amplifiers can be configured internally as a follower, as an amplifier with a non-inverting gain ranging from 2 to 64 or with inverting gain ranging from -1 to -63. The positive input can be connected to the internal DAC. The output can be connected to the internal ADC."
