Product Summary

The MAX274AEWI is a continuous-time active filter consisting of independent cascadable 2nd-order sections. Each section can implement any all-pole bandpass or lowpass filter response, such as Butter- worth, Bessel, and Chebyshev, and is programmed by four external resistors. The MAX274AEWI provides lower noise than switched-capacitor filters, as well as superior dynamic performance - both due to the confitinuous-time design. Since continuous-time filters do not require a clock, aliased and clock noise are eliminated with the MAX274AEWI.
