    would wiring an AN5276,,,,,

    Would wiring an AM5276 be the same as an opamp?

    it has a standby feature and muting, but I don't want to use them features.

    Do NOT touch heatsinks when testing for voltages as they may be LIVE!

    For what use? Yes there's going to be an opamp-like stage in it, suitable for audio frequencies, but unlike a typical opamp it's not going to have the bandwidth outside of audio frequencies and may sound less detailed (may depend on the opamp compared against too).

    See the datasheet page 5, pin no. 7 diagram, the "Pre amp." is your opamp but there's not an adjustable gain since the voltage divider resistors in the feedback loop are built in (30 Kohm / 600 ohm), so in certain circuits it could be an acceptable replacement for some opamps, but not a universal one. You must also consider whether that gain ( 30K/600) = 50X is right for the project.

    Maybe I misunderstood your question. If you were asking if it sits in a circuit with the same support components as an opamp would in an audio circuit, yes it would be the same as a single (power) rail opamp doing the same job, except the feedback loop is built in.

    Panasonic didn't include much in the way of graphs to assess the performance, but often with a single rail chip like this you'll get better performance if you increase the RF (ripple filter) capacitor amount to more than 100uF, perhaps going up to 470uF, and also there is a mistake on the linked datasheet Application Circuit Example on pg. 7 where they label the RF pin as "1" when it is really pin 3.
