It is suitable for stereo and bridge amplifier application of radio cassette tape recorder. Outline Drawing F E AT U R E S z High output power St ereo: Po=2 .3W (Typ) at Vcc=9V, RL=4 Ω Bridge: Po=4.7W (Typ) at Vcc=9V, R L=8 Ω z Low switching distortion at high frequency. z Small shock noise at the time of power on/off due to a built-in muting circuit z Good ripple rejection due to a built-in ripple filter. z Good channel separation. z Soft tone at the time of output saturation. z Closed loop voltage gain fixed 45dB (Bridge: 51dB) but availability with external resistor added. z Minimum number of external parts required. z Easy to design radiator fin.
