Universal and Bandpass Filters
General Description
The MAX263/264 and MAX267/268 CMOS switched-
capacitor active filters are designed for precision
filtering applications. Center frequency, o, and oper-
ating mode are all selected via pin-strapped inputs.
The MAX263/264 uses no external components for a
variety of bandpass, lowpass, highpass, notch and
allpass filters. The MAX267/268 is dedicated to
bandpass applications and includes an uncommitted
op-amp. Two second-order filter sections are included
in both devices.
An input clock and a 5-bit programming input
precisely set the filter center/corner frequency. Q is
also programmed from 0.5 to 64. Separate clock
inputs for each filter half operate with either an
external clock or a crystal.
The MAX263 and 267 operate with center frequencies
up to 57kHz while the MAX264 and 268 extend the fo
range to 140kHz by employing lower fCLK/fo ratios. The
MAX263/264 is supplied in 28 pin wide DIP and small
outline packages while the MAX267/268 is supplied in
24 pin narrow DIP and wide SO packages. All devices
are available in commercial, extended, and military
temperature ranges.
