MAX274AENG+

MAX274AENG+ 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 with, Bessel, Chbyshev, and is programmed by for external resistor. It provides lower noise than switched capacitor filters, as well as superior dynamic performance due to the continuous time design. Since continuous time filters do not require a clock, aliased and clock noise are eliminated. Application includes low distortion anti aliasing filters, DAC output smoothing filters, modems, audio/sonar/avionics frequency filtering, and vibration analysis.
