TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8227P
Low Frequency Power Amplifier
TA8227P is an audio power IC with built-in two channels developed for portable radio cassette tape recorder with power ON/OFF switch. Because of the parts reduction and DIP (Dual Inline Package), space merit is remarkable. Thermal shut down protection circuit is built in.
