MAXIM MAX7418 MAX7425 Manual

The MAX7418~MAX7425 5th-order low-pass, switched-capacitor filters (SCFs) operate from a single +5V (MAX7418~MAX7421) or +3V (MAX7422~MAX7425) supply. These devices draw only 3mA of supply current and allow corner frequencies from 1Hz to 45kHz, mak- ing them ideal for low-power post-DAC filtering and anti- aliasing applications.
