External Components Description
Components
Functional Description
1.
C
i
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminals. It also creates a
highpass filter with the internal R
i. The designer should note that10kOhm<(Ri)<110kOhm.Therefore fc =
1/(2
πR
iCi). Refer to the section, Proper Selection of External Components, for an explanation of how to
determine the value of C
i.
2.
C
S
Supply bypass capacitor which provides power supply filtering. Refer to the Power Supply Bypassing
section for information concerning proper placement and selection of the supply bypass capacitor.
3.
C
B
Bypass pin capacitor which provides half-supply filtering. Refer to the section, Proper Selection of
External Components, for information concerning proper placement and selection of C
B.
