TA8227P

SUM TA8227P LOW FREQUENCY POWER AMPLIFIER TA8227P GENERAL DESCRIPTION TA8227P 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.
