Components
Functional Description
1.
C
i
Input coupling capacitor blocks DC voltage at the amplifier’s input terminals. It also creates a highpass
filter with the internal R
i that produces an fc = 1/(2πRiCi) (10k≤ Ri ≤ 100k). Refer to the Application
Information section, Selecting External Components, for an explanation of determining the value of C
i.
2.
C
S
The supply bypass capacitor. Refer to the Power Supply Bypassing section for information about
properly placing, and selecting the value of, this capacitor.
3.
C
B
The capacitor, C
B, filters the half-supply voltage present on the BYPASS pin. Refer to the Application
Information section, Selecting External Components, for information concerning proper placement and
selecting C
B’s value.
