MAX261BENG+ Product Details

The MAX261BENG+ is a microprocessor programmable universal active filter in 24 pin DIP package. It allows microprocessor control of precise filter functions, No external components are required for a variety of bandpass, lowpass, highpass, notch and allpass configurations. Each device contains two second order filter sections that place centre frequency, Q and filter operating mode under programmed control. An input clock, along with a 6bit f0 program input, determines the filter's centre or corner frequency without affecting other filter parameters and filter Q is also programmed independently. Separate clock inputs for each filter section operate with a crystal, RC network or external clock generator. It is used in µP-tuned filters, anti-aliasing filters, digital signal processing, adaptive filters, signal analysis and phase-locked loops.
