Functional Descriptions
1. RI
2. CI
3. RF
4. CS
The inverting input resistor which sets the closed-loop gain in conjunction with Rf. This
resistor also forms a high pass filter with CI at fc=1/(2πRICI)
The input coupling capacitor blocks the DC voltage at the amplifier’s input terminals. Also
creates a high pass with RI at fc=1/(2πRICI). Refer to the section, Proper Selection of
External Components, for an explanation of how to determine the value of CI.
The feedback resistor which sets closed-loop gain in conjunction with RI.
The 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. CB
The bypass pin capacitor which provides half-supply filtering. Refer to the Proper
Selection of External Components section for information concerning proper placement
and selecting CB’s value.
