External Components Description
Components
Functional Description
1.
R
i
Inverting input resistance that 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 that blocks the DC voltage at the amplifiers 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 that sets the closed-loop gain in conjunction with R
i.
4.
C
S
Supply bypass capacitor that 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 that provides half-supply filtering. Refer to the section, Proper Selection of External
Components, for information concerning proper placement and selection of C
B.
