Product Overview

The MAX261BCWG+ from Maxim Integrated Products is a microprocessor programmable universal active filter in 24 pin WSOIC package. This CMOS dual second order universal switched capacitor active filter allows microprocessor control of precise filter functions. No external components are required for a variety of bandpass, lowpass, highpass, notch and all pass configurations. 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 filter's centre or corner frequency without affecting other filter parameters. The filter Q is also programmed independently and 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, DSP, adaptive filters and phase-locked loops.
  • Supply voltage range is 2.37V to 6.3V
  • Operating temperature range from 0°C to +70°C
  • Handles centre frequencies to 57KHz, 64 step centre frequency control, clock to f0 ratio is 2%
  • Filter design software, microprocessor interface
  • Power supply current is 20mA (max) at TA = TMIN to TMAX CMOS level logic inputs
  • Slew rate 6V/µs, gain bandwidth product of 2.5MHz
  • 128 -step Q control
  • Independent Q and f0 programming
  • Output signal circuit current, source is 50mA and sink is 2mA
