Components description
Inverting input resistor which sets the closed loop gain in conjunction with Rfeed. This
resistor also forms a high pass filter with Cin (fc = 1 / (2 x Pi x Rin x Cin))
Input coupling capacitor which blocks the DC voltage at the amplifier input terminal
Feed back resistor which sets the closed loop gain in conjunction with Rin
Supply Bypass capacitor which provides power supply filtering
Bypass capacitor which provides half supply filtering
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 RL x Cout))
These 2 resistors form a voltage divider which provide a DC biasing voltage (Vcc/2) for
the 2 amplifiers.
Closed loop gain = -Rfeed / Rin
