General Description
The MAX291/MAX292/MAX295/MAX296 are easy-to-use,
8th-order. lowpass, switched-capacitor filters that can be
set up with corner frequencies from 0.1Hz to 25kHz
(MAX291/MAX292) or 0.1Hz to 50kHz (MAX295/MAX296).
The MAX291/MAX295 Butterworth filters provide maxi-
mally flat passband response, and the MAX292/MAX296
Bessel filters provide low overshoot and fast settling. All
four filters have fixed responses, so the design task is
limited to selecting the clock frequency that controls the
filter's corner frequency.
An external capacitor is used to generate a clock using
the internal oscillator, or an external clock signal can be
used. An uncommitted operational amplifier (noninverting
input grounded) is provided for building a continuous-
time lowpass filter for post-filtering or anti-aliasing.
Produced in an 8-pin DlP/SO and a 16-pin wide so
package, and requiring a minimum of external compo-
nents, the MAX291 series delivers very aggressive per-
formance from a tiny area.
