CD8227GP
LOW FREQUENCY POWER AMPLIFIER
GENERAL DESCRIPTION
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.
