Product Summary

The UAF42AP is a filter design program for the UAF42 universal active filter. The UAF42AP contains the op amps, matched resistors, and precision capacitors needed for a state-variable filter pole-pair. A fourth, uncommitted precision op amp is also included on the die. The UAF42AP DOS-compatible program guides you through the design process and automatically calculates component values. Low-pass, high-pass, band-pass, and band-reject (or notch) filters can be designed.

Parametrics

UAF42AP absolute maximum ratings: (1)BW: 4MHz typ; (2)FPR: 160KHz typ; (3)SP: 10V/μs typ; (4)VOS: 5000μV max; (5)VOS/dT: ±3μV/℃ max typ; (6)noise at 10kHz: 10nV/Hz; (7)CCM: 4pF.

Features

UAF42AP features: (1)Better rate of attenuation beyond the pass-band than Butterworth; (2)Flat magnitude response in pass-band with steep rate of attenuation in transition-band; (3)Best step response—very little overshoot or ringing.
