2.4 Operational Amplifier (OPA)

The Operational Amplifier (OPA) module can be used as a signal conditioning element in sensing and measurement applications. The OPA module can be used as programmable gain amplifier for the ADC input signals in low-voltage range, and the OPA module output is internally connected to the ADC input channel.

Figure 2-4 shows a simplified diagram of the OPA module interconnection to other peripherals of PIC16F17146 family of microcontrollers.
