AA8227PH-E1

Preliminary Datasheet DUAL AUDIO POWER AMPLIFIER General Description The AA8227 is a monolithic dual audio power amplifier with built-in power on/off switch. It is designed for use in portable radio cassette, tape recorder and other audio products. Because it needs only few external components to work, an audio system adopting AA8227 will have a remarkable merit to save system space. This IC is available in HDIP-12 package.
