TEXAS INSTRUMENTS  UAF42AP  Analogue Filter, Universal, 2nd, 1, 6 V, 18 V, DIP

Product Overview

The UAF42AP is an 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.
  • Versatile (low-pass, high-pass and band-pass, band-reject)
  • Simple design procedure
  • Accurate frequency and Q
  • Includes on-chip 1000pF ±0.5% capacitors
  • Green product and no Sb/Br
