No, at least not as a standard opamp. The external signal ACMPO is a digital output, so it tends to slip either to Vdd or Vss depending on the actual analog level of ACMPO (internally). Thus you can't close the feedback via standard resistor network.

 

I've tested that, also wanted to use that opamp similarly.

Hi Pavel, thanks a lot for your information. I guess I mixed the MJ60 ACMPOV2 with Operational Amplifiers on MSP430Fxx. – The on chip Amplifier is useful especially for sensor applications.
