LA4555 Datasheet - Sanyo

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 .
