MAX260BCNG

The MAX260/MAX261/MAX262 CMOS dual secondorder universal switched-capacitor active filters allow
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 center frequency, Q, and filter operating mode under programmed control.
An input clock, along with a 6-bit f0 program input,
determine the filter’s center or corner frequency without
affecting other filter parameters. The filter Q is also programmed independently. Separate clock inputs for
each filter section operate with either a crystal, RC network, or external clock generator.
