Application Notes
- Build a 3-Phase Sine Wave Generator with the UAF42PDF, 33 Kb, File published: Oct 4, 2000
A three phase sine wave oscillator can be built using one UAF42 state variable filter along with some resistors and diodes. Three output nodes are available; highpass out, bandpass out and lowpass out. The signal at the bandpass and lowpass out nodes are 90В° and 180В° out of phase, respectively, with the highpass out node. An on-chip auxiliary op amp is available for use as a buffer or gain - Design a 60Hz Notch Filter with the UAF42PDF, 71 Kb, File published: Oct 4, 2000
The UAF42 is a monolithic, time-continuous, 2nd-order active filter building block for complex and simple filter designs. It uses the classical state-variable analog architecture with a summing amplifier plus two integrators. This topology offers low sensitivity of filter design parameters fo (natural frequency) and Q to external component variations along with simultaneous high-pass, l - Simple Filter Turns Square Waves into Sine WavesPDF, 61 Kb, File published: Sep 27, 2000
Many signals are digitally generated or transmitted as square waves. It is often desirable to convert these signals into sine waves. For example, the 350Hz, 440Hz, 480Hz, and 620Hz telephone supervisory tones transmitted over fiber-optics may appear at curb-side as square waves. To be used in telephone equipment it is desirable to convert the square waves into low-distortion sine waves. This can b - Filter Design Program For The UAF42 Universal Active FilterPDF, 540 Kb, File published: Sep 27, 2000
Although active filters are vital in modern electronics, their design and verification can be tedious and time consuming. To aid in the design of active filters, Burr-Brown provides a series of FilterProВ™ computer-aided design programs. Using the FILTER42 program and the UAF42 it is easy to design and implement all kinds of active filters. The UAF42 is a monolithic IC which contains the op am - Digitally Programmable, Time-Continuous Active FilterPDF, 32 Kb, File published: Sep 27, 2000
Programmable active filters have increased in popularity over the past decade. With the advent of switched capacitor topologies, filter parameters such as the natural frequency and filter Q can be changed simply by varying the clock frequency. But switched capacitor filters are sampled data systems and are subject to anomalies such as clock feedthrough noise and aliasing errors.
