Stereo: Po=2.4W(Typ) at Vcc=9V,RL=4Ω,THD=10%

Bridge: Po=4.7W(Typ) at Vcc=9V,RL=8Ω,THD=10%

*Small shock noise at the time of power on/off due to a built-in muting circuit

*Good ripple rejection due to a built-in ripple filter

*Good channel separation

*Soft tone at the time of output saturation

*Closed loop voltage gain fixed 45dB (Bridge: 51dB) but availability with external resistor added
