Active filter circuits used in audio circuitry, especially the bass, treble, etc.. general op amp for audio integrated circuits are built on a variety of circuits quite simple overall structure is composed of resistors and capacitors on the main controller integrated op amp. Scheme not specified in the application note this integrated power leg tl082, tl071, NE5532, tl074, tl084, tl081 op amp can be used to integrate the supply leg is in the datasheet information.
