Product Summary

The MAX7427CUA is a kind of 5th-order, lowpass, elliptic, switched-capacitor filter. The MAX7427CUA operates from a single +3V supply. The MAX7427CUA draw only 0.8mA of supply current and allow corner frequencies from 1Hz to 12kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. The MAX7427CUA can be put into a low-power mode, reducing supply current to 0.2μA. The MAX7427CUA delivers 37dB of stopband rejection and a sharp rolloff with a transition ratio of 1.25. Its fixed response limits the design task to selecting a clock frequency.The MAX7427CUA is widely used in ADC anti-aliasing, CT2 base stations, post-DAC filtering and speech processing.
