LA4445 - 5.5W 2-Channel AF Power Amplifier

of External Parts C1 (C2) : Feedback capacitor Low cutoff frequency fL depends on this feedback capacitor. Increasing the capacitor value makes the starting time later C3 (C4) : Bootstrap capacitor If the capacitor value is decreased, the output at low frequencies goes lower. (Recommended value : 47.
