Universal Active Filter

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.
A DOS-compatible Filter design program allows easy implementation of many Filter types, such as Butterworth, Bessel, and Chebyshev. A fourth, 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 a 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 -25C to +85C temperature range.
