AA8227
General Description
Features
The AA8227 is a monolithic dual audio power ampli-
fier with built-in power on/off switch. It is designed for
use in portable radio cassette, tape recorder and other
audio products.

Low Popping Noise at Power On
Soft Clip
Few External Components
Operating Supply Voltage Range: 5 to 15 V
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.
