Functional Description

Rin

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))

Cin

Rfeed

Cs

Cb

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

Cout

Rpol

Av

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
