Application component information
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’s input terminal.
Rfeed1,2
Feedback resistor that sets the closed loop gain in conjunction with Rin.
AV= Closed Loop Gain= -Rfeed/Rin.
Cs
Supply output capacitor that provides power supply filtering.
Cb
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)).
