The purpose of the OPA peripheral integrated into the MSPM0xx MCU platform is to provide a way to buffer or amplify analog signals in a system without the need of discrete op-amps.
The OPA is based off of a high-performance factory trimmed amplifier core accompanied with a programmable gain stage feedback loop, configurable input muxes, and a burnout current source used to monitor sensor health.
OPA features include:
Figure 14-1 shows the functional block diagram of the OPA peripheral.
