19-0352; Rev 2; 7/02 MAX260/MAX261/MAX262 Microprocessor Programmable Universal Active Filters General Description The MAX260/MAX261/MAX262 CMOS dual secondorder universal switched-capacitor active filters allow microprocessor control of precise filter functions. No external ponents 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...
