External Components Description (Figure 1)
Components
Functional Description
1.
R
i
Inverting input resistance which sets the closed-loop gain in conjunction with R
F. This resistor also forms a
high pass filter with C
i at fc = 1/(2
π R
iCI).
2.
C
i
Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminals. Also creates a
highpass filter with R
i at fc = 1/(2
π R
iCi). Refer to the section, Proper Selection of External Components,
for an explanation of how to determine the value of C
i.
3.
R
F
Feedback resistance which sets the closed-loop gain in conjunction with R
i.
4.
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.
5.
C
B
Bypass pin capacitor which provides half-supply filtering. Refer to the Proper Selection of External
Components for information concerning proper placement and selection of C
B.
