UNIVERSAL ACTIVE FILTER

Check for Samples: UAF42

FEATURES

DESCRIPTION

•

VERSATILE:

The UAF42 is a universal active filter that can be

configured for a wide range of low-pass, high-pass,

and band-pass filters. It uses a classic state-variable

analog architecture with an inverting amplifier and two

integrators. The integrators include on-chip 1000pF

capacitors trimmed to 0.5%. This architecture solves

one of the most difficult problems of active filter

design—obtaining tight tolerance, low-loss capacitors.

MONOLITHIC REPLACEMENT FOR UAF41

uncommitted FET-input op amp (identical to the other

three) can be used to form additional stages, or for

special filters such as band-reject and Inverse

Chebyshev.

The classical topology of the UAF42 forms

time-continuous filter, free from the anomalies and

switching noise associated with switched-capacitor

filter types.

The UAF42 is available in 14-pin plastic DIP and

SOIC-16 surface-mount packages, specified for the

–25°C to +85°C temperature range.
