Component

Functional Description

This is the input coupling capacitor. It blocks the DC voltage at, and couples the input signal to the

Cin

amplifier’s input terminals. Cin also creates a highpass filter with the internal input impedance Zin at

Fc = 1 / (2π x Zin x Cin).

Cs

This is the Supply Bypass capacitor. It provides power supply filtering.

CB

This is the Bypass pin capacitor. It provides half-supply filtering.
