5.4 Operational Amplifier (OPA)

The STM32G0 family of devices does not offer an integrated Operational Amplifier (OPA) peripheral, but when migrating from the STM32G0 to MSPM0 family, you can make use of the MSPM0 internal OPAs to replace external discrete devices, or to buffer internal signals as necessary. The MSPM0 OPA modules are completely flexible, and can individually, or in combination, replace many discrete amplifiers in sensing or control applications. The primary features of the MSPM0 OPA modules are included in #GUID-DC5B5210-8513-4E2A-8AC7-61BCBF737C1A/GUID-C4BC7F80-61EF-4C66-B678-3F5AB1EFCE02, and examples of common OPA configurations you can recreate are included in OPA code examples
