5 / 15 page External Components Description (Figure 1) Components Functional Description 1. R i Inverting input resistance that sets the closed-loop gain in conjunction with R f. This resistor also forms a high pass filter with C i at fC= 1/(2 π R iCi). 2. C i Input coupling capacitor that blocks the DC voltage at the amplifiers input terminals. Also creates a highpass filter with R i at fc = 1/(2 π R iCi). Refer to the section, Proper Selection of External Components, for an explanation of how to determine the value of C i. 3. R f Feedback resistance that sets the closed-loop gain in conjunction with R i. 4. C S Supply bypass capacitor that provides power supply filtering. Refer to the Power Supply Bypassing section for information concerning proper placement and selection of the supply bypass capacitor. 5. C B Bypass pin capacitor that provides half-supply filtering. Refer to the section, Proper Selection of External Components, for information concerning proper placement and selection of C B.
