Components

Functional Description

1.

R

i

Inverting input resistance which sets the closed-loop gain in conjunction with R

forms a high pass filter with C

π R

2.

C

i

Input coupling capacitor which blocks DC voltage at the amplifier’s input terminals. Also creates a

highpass filter with R

π R

3.

R

f

Feedback resistance which sets closed-loop gain in conjunction with R

4.

C

S

Supply bypass capacitor which provides power supply filtering. Refer to the Application Information

section for proper placement and selection of supply bypass capacitor.

5.

C

B

Bypass pin capacitor which provides half supply filtering. Refer to Application Information section for

proper placement and selection of bypass capacitor.

6. C

f (Note 10)

Used when a differential gain of over 10 is desired. C

which bandwidth limits the amplifier and prevents high frequency oscillation bursts. f

π R

Note 10: Optional component dependent upon specific design requirements. Refer to the Application Information section for more in formation.
