Product Summary

The max274acng is a continuous-time active filter consisting of independent cascadable 2nd-order sections. The max274acng 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 max274acng provides lower noise than switched-capacitor filters, as well as superior dynamic performance-both due to the contimuous-time design. Since continuous-time filters do not require a clock, aliased and clock noise are eliminated with the max274acng. The applications of the max274acng include Low-distortion anti-aliasing filters, DAC output smoothing filters, Modems, Audio/Sonar/Avionics frequency filtering, Vibration analysis.
