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.
