AV L, R
Inverting input resistors which sets the closed loop gain in
conjunction with Rfeed. These resistors also form a high pass
filter with CIN (fc = 1 / (2 x Pi x RIN x CIN))
Input coupling capacitors which blocks the DC voltage at the
amplifier input terminal
Feedback resistors which sets the closed loop gain in
conjunction with RIN
Supply Bypass capacitor which provides power supply filtering
Bypass pin capacitor which provides half supply filtering
Closed loop gain in BTL configuration = 2 x (RFEED / RIN) on
each channel
2/29
