●Description of External components

①Input coupling capacitor (C1,C2)

It makes a Input coupling capacitor 0.1µF.

Input impedance is 75kΩ (Typ.).

It sets cutoff frequency fc by the following formula by input coupling capacitor C1(=C2) and input impedance Ri.

fc 

[Hz]

2π Ri C1

In case of Ri=75kΩ, C1 (=C2)=0.1µF, it becomes fc = about 21 Hz.

②Power decoupling capacitor (C3)

It makes a power decoupling capacitor 10 µF.

When making capacitance of the power decoupling capacitor, there is an influence in the Audio characteristic.

When making small, careful for the Audio characteristic at the actual application.
