Components

Functional Description

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

f in conjunction with Rf creates a low-pass filter

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

C = 1/(2π Rf Cf)

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