LA4550 Datasheet - Sanyo

LA4550 2-Channel AF Power Amplifier

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