Functional Description
RIN

RFEED
CS
CB
Inverting input resistor which sets the closed loop gain in conjunction with RFEED. This resistor also
forms a high pass filter with CIN (fcl = 1 / (2 x Pi x RIN x CIN)). Not needed in fixed gain versions.
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminal
Feedback resistor which sets the closed loop gain in conjunction with RIN.
AV= Closed Loop Gain= 2xRFEED/RIN. Not needed in fixed gain versions.
Supply Bypass capacitor which provides power supply filtering.
Bypass capacitor which provides half supply filtering.
