KS2206B
FEATURES
- High output power Stereo : PO = 2.3W(Typ) at VCC = 9V, RL = 4Ω . Bridge : PO = 4.7W (Typ) at VCC = 9V, RL = 8Ω
- Low switching distortion at high frequency.
- 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 45d B (Bridge : 51d B) but availability with external resistor added.
- Minimum number of external parts required.
- Easy to design radiator fin.
