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