External Components Description

(Figure 2 and Figure 3)

Components

Functional Description

1. Ri

Inverting input resistance which sets the closed-loop gain in conjunction with Rf. This resistor also forms a high pass

filter with Ci at fC = 1 / (2π Ri Ci).

2. Ci

Input coupling capacitor which blocks DC voltage at the amplifier's input terminals. Also creates a high pass filter with

Ri at fC = 1 / (2π Ri Ci).

3. Rf

Feedback resistance which sets closed-loop gain in conjunction with Ri.

4. CSApplication

Supply bypass capacitor which provides power supply filtering. Refer to for proper placement and selection of supply

Information

bypass capacitor.

5. CB

Bypass pin capacitor which provides half supply filtering. Refer to Application Information for proper placement and

selection of bypass capacitor.

6. Cf

(1)

Cf in conjunction with Rf creates a low-pass filter which bandwidth limits the amplifier and prevents possible high

frequency oscillation bursts. fC = 1 / (2π Rf Cf)

(1)

Optional component dependent upon specific design requirements. Refer to Application Information for more information.
