External Components Description
(Figure 1 )
Components
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 f
c
=
1/(2
π

C
i
). 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
