That's very similar to an op-amp, but its actually an AF power amp.
The spec sheet lists it as a power op amp, so I think it's a more general purpose amp then those labeled as audio power amps.The schematic symbol for many audio speaker amplifiers look like normal opamps. They are not. Audio speaker amplifiers are weird, squirrely, and tempermental. They require careful decoupling plus things like the zobell network to prevent breaking into oscillation. Just a warning...
There's a sort of grey area between power op-amps and audio power amplifiers, some are equally at home in either application - some are a little more fussy.The spec sheet lists it as a power op amp, so I think it's a more general purpose amp then those labeled as audio power amps.
Page 7 of the datasheet has some notes about stability.
