Product Summary

The UAF42AU is a universal active filter. Although the UAF42AU active filter is vital in modern electronics, its design and verification can be tedious and time consuming. To aid in the design of active filters, Burr-Brown provides a series of FilterPro. computer-aided design programs. Using the FILTER42 program and the UAF42AU it is easy to design and implement all kinds of active filters. The UAF42AU is a monolithic IC which 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.
