LA4550 Datasheet (Sanyo) - 2-Channel AF Power Amplifier

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
