Components
Functional Description
1.
Ri
Combined with Rf, this inverting input resistor sets the closed-loop gain. Ri also forms a high pass filter with Ci at fc =
1/(2
πRiCi).
2.
Ci
This input coupling capacitor blocks DC voltage at the amplifier's terminals. Combined with Ri, it creates a high pass
filter 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.
3.
Rf
Combined with Ri, this is the feedback resistor that sets the closed-loop gain: Av = 2(RF/Ri).
4.
CS
This is the power supply bypass capacitor that filters the voltage applied to the power supply pin. Refer to the
Application Information section for proper placement and selection of Cs.
5.
CB
This is the bypass pin capacitor that filters the voltage at the BYPASS pin. Refer to the section, Proper Selection of
External Components, for information concerning proper placement and selection of CB.
