Description of External components
1. Input coupling capacitor (C1, C2)
It makes an Input coupling capacitor 0.47F.
It sets cutoff frequency fc by the following formula by input coupling capacitor C1 (=C2) and input impedance Ri.
In case of C1 (=C2) =0.47F
BD5632NUX Ri =100k : fc=3.5Hz
BD5634NUX Ri =50k : fc=7Hz
BD5638NUX Ri =25k : fc=14Hz
2. Power decoupling capacitor (C3)
It makes a power decoupling capacitor 10F.
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.
