Functional description
Cs
Supply bypass capacitor that provides power supply filtering.
Cb
Bypass capacitor that provides half supply filtering.
Rfeed
Feedback resistor that sets the closed loop gain in conjunction with Rin
AV = closed loop gain = Rfeed/Rin.
Rin
Inverting input resistor that sets the closed loop gain in conjunction with Rfeed.
Cin
Optional input capacitor making a high pass filter together with Rin.
(FCL = 1/(2πRinCin).
