Components

Functional Description

Ri

Inverting input resistance which sets the closed-loop gain in conjunction with

Rf. This resistor also forms a high pass filter with Ci at fc = 1/(2πRi*Ci).

Ci

Input coupling capacitor which blocks the DC voltage at the amplifiers input

terminates. Also creates a high-pass filter with Ri at fc = 1/(2πRi*Ci).

Rf

Feedback resistance which sets the closed-loop gain in conjunction with Ri.

Cs

Supply bypass capacitor which provides power supply filtering.

Cb

Bypass pin capacitor which provides half-supply filtering. Refer to the section.
