Components

Functional description

CS1, CS2

Cin

Supply capacitor that provides power supply filtering.

Input coupling capacitors (optional) that block the DC voltage at the amplifier input

terminal. The capacitors also form a high pass filter with Zin

(Fcl = 1 / (2 x π x Zin x Cin)). Be aware that value of Zin is changing with gain setting.
