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 a maximally 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 generates 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 DIP/SO and a 16-pin wide SO package and requiring a minimum of external components.

The MAX291ESA series delivers very aggressive performance from a tiny area.
