MAX260BMRG

The MAX260/MAX261/MAX262 CMOS dual second-order universal switched-capacitor active filters allow microprocessor control of precise filter functions. No external components are required for various bandpass, lowpass, highpass, notch, and all pass configurations. Each device contains two second-order filter sections that place centre frequency, Q, and filter operating mode under programmed control. An input clock and a 6-bit f0 program input determine the filter's centre or corner frequency without affecting other filter parameters. The filter Q is also programmed independently. Separate clock inputs for each filter section operate with a crystal, RC network, or external clock generator. 

The MAX260BMRG has offset and DC specifications superior to the MAX261 and MAX262 and a center frequency (f0) range of 7.5kHz. The MAX261 handles center frequencies to 57kHz, while the MAX262 extends the center frequency range to 140kHz by employing lower clock-to-f0 ratios. All devices are available in 24-pin DIP and small-outline packages in commercial, extended, and military temperature ranges.
