Component

Functional description

Rin1,2

Inverting input resistor that 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)]

Cin1,2

Input coupling capacitor that blocks the DC voltage at the amplifier input terminal

Rfeed1,2

Feedback resistor that sets the closed loop gain in conjunction with Rin.

AV= closed loop gain= -Rfeed/Rin

Supply output capacitor that provides power supply filtering

Bypass capacitor that provides half supply filtering

Cout1,2

Output coupling capacitor that blocks the DC voltage at the load input terminal.

This capacitor also forms a high pass with RL [Fc = 1 / (2 x Pi x RL x Cout)]
