MAX7422 5th-Order / Lowpass / Switched-Capacitor Filters

The MAX7418 *MAX7425 5th-order, low-pass, switchedcapacitor 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, making them ideal for low-power.
