LOW FREQUENCY POWER AMPLIFIER

GENERAL DESCRIPTION

Outline Drawing

CD8227GP is audio power IC with built-in

two Channels developed for portable radio

cassette tape recorder with power ON/OFF

switch.

Thermal

shut

down

protection

circuit is built in. Because of the parts

reduction and DIP (Dual in line package),

space merit is remarkable.

FEATURES
