External Components Description (Figures 1, 2)
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/(2π Ri Ci).
2. C
i
Input coupling capacitor which blocks DC voltage at the amplifier’s input terminals. Also creates a highpass
filter with R
i at fC = 1/(2π Ri Ci).
3. R
f
Feedback resistance which sets closed-loop gain in conjunction 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 supply bypass capacitor.
5. C
B
Bypass pin capacitor which provides half supply filtering. Refer to the Application Information section for
proper placement and selection of bypass capacitor.
6. C
f (Note 9)
C
f in conjunction with Rf creates a low-pass filter which bandwidth limits the amplifier and prevents possible
high frequency oscillation bursts.
f
C = 1/(2π Rf Cf)
Note 9: Optional component dependent upon specific design requirements. Refer to the Application Information section for more information.
