Overview
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 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.
The MAX260 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 57k...
