TA8227P LOW FREQUENCY POWER AMPLIFIER

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 .
