Components
Functional Description
R
IN L,R
Inverting input resistors which sets the closed loop gain in conjunction with
R
feed
. 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
V L, R
Closed loop gain in BTL configuration =
2 x (R
FEED
/ R
IN
) on each channel.
