General Description
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, making them ideal for low-power post-DAC filtering and anti
aliasing applications. They feature a shutdown mode that reduces supply current to 0.2µA.
