Components
Functional Description
CS
Supply Bypass capacitor which provides power supply filtering.
CB
Bypass capacitor which provides half supply filtering.
RFEED
Feedback resistor which sets the closed loop gain in conjunction with RIN
AV= Closed Loop Gain= RFEED/RIN.
RIN
Inverting input resistor which sets the closed loop gain in conjunction with RFEED.
CIN
Optional input capacitor making a high pass filter together with RIN. (fcl = 1 / (2 x Pi x RIN x CIN)
