External Components Description
(Refer to Figure 1.)
The Inverting input resistance, along with Rf, set the closed-loop gain. Ri, along with Ci, form a high pass
filter with fc = 1/(2πRiCi).
The input coupling capacitor blocks DC voltage at the amplifier’s input terminals. Ci, along with Ri, create a
highpass filter with fc = 1/(2πRiCi). Refer to the section, SELECTING PROPER EXTERNAL
COMPONENTS, for an explanation of determining the value of Ci.
The feedback resistance, along with Ri, set the closed-loop gain.
Cs The supply bypass capacitor. Refer to the POWER SUPPLY BYPASSING section for information about
properly placing, and selecting the value of, this capacitor.
CB The capacitor, CB, filters the half-supply voltage present on the BYPASS pin. Refer to the SELECTING
PROPER EXTERNAL COMPONENTS section for information concerning proper placement and selecting
