External Components Description
Components
Functional Description
1. R
i
Inverting input resistance which sets the closed-loop gain in conjuction with R
f. This resistor also forms
a high pass filter with C
i at fc =1/(2
πR
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
πR
iC i). Refer to the section, Proper Selection of External
Components, for and explanation of how to determine the value of C
i.
3. R
f
Feedback resistance which sets closed-loop gain in conjuction with R
i.
4. C
S
Supply bypass capacitor which provides power supply filtering. Refer to the Application Information
section for proper placement and selection of the supply bypass capacitor.
5. 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.
6. C
O
Output coupling capacitor which blocks the DC voltage at the amplifier’s output. Forms a high pass
filter with R
L at fO = 1/(2
πR
LCO)
