19-1821; Rev 0; 11, 00 MAX7418 MAX7425 5th-Order, Lowpass, Switched-Capacitor Filters General Description 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 1H- to 45kHz, making them ideal for low-power post-DAC filtering and antialiasing applications. They feature a shutdown mode that reduces supply current to 0.2
