Component
Functional Description
This is the input coupling capacitor. It blocks the DC voltage at, and couples the input signal to the
C_in
amplifier’s input terminals. Cin also creates a highpass filter with the internal input impedance Zin at
Fc = 1 / (2π x Zin x Cin).
C_s
This is the Supply Bypass capacitor. It provides power supply filtering.
C_B
This is the Bypass pin capacitor. It provides half-supply filtering.
