LA4555 - 2-Channel AF Power Amplifier
of External Parts C1 (C2) : Feedback capacitor.
The low cutoff frequency is determined by the following formula.
1 fL : Low cutoff frequency fL= 2πC1Rf Rf : Feedback resistance Since this capacitor as well as decoupling capacitor affects the starting time, the capacitor value must be fixed with the
