Functional Description
R
IN1,2
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
(fc = 1 / (2 x Pi x R
IN
x C
IN
)) .
Not needed in fixed gain versions.
C
IN1,2
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminal.
R
FEED1,2
Feedback resistor which sets the closed loop gain in conjunction with R
IN
.
A
V
= Closed Loop Gain= -R
FEED
/R

.
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.
C
OUT1,2
Output coupling capacitor which blocks the DC voltage at the load input terminal.
This capacitor also forms a high pass filter with RL (fc = 1 / (2 x Pi x R
L
x C
OUT
)).
