Functional Description
R
IN L,R
Inverting input resistors which sets the closed loop gain in
conjunction with Rfeed. These resistors also form a high pass
filter with C
IN
(fc = 1 / (2 x Pi x R
IN
x C
IN
))
C
IN L,R
Input coupling capacitors which blocks the DC voltage at the
amplifier input terminal
R
FEED L,R
Feedback resistors which sets the closed loop gain in
conjunction with R
IN
C
S
Supply Bypass capacitor which provides power supply filtering
C
B
Bypass pin capacitor which provides half supply filtering
A
