Components Functional Description
R
IN
Inverting input resistor which sets the closed loop gain in conjunction with R
FEED
. This resistor also
forms a high pass filter with C
IN
(fcl = 1 / (2 x Pi x R
IN
x C
IN
)). Not needed in fixed gain versions.
C
IN
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminal
R
FEED
Feedback resistor which sets the closed loop gain in conjunction with R
IN
.

IN
. Not needed in fixed gain versions.
C
S
Supply Bypass capacitor which provides power supply filtering.
C
B
Bypass capacitor which provides half supply filtering.
