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.
The MAX7418‑MAX7425 family are 5th‑order low‑pass switched‑capacitor filters that operate from a single +5 V (MAX7418‑MAX7421) or +3 V (MAX7422‑MAX7425) supply. They draw only 3 mA in normal operation and feature a shutdown mode that reduces current to 0.2 µA, making them suitable for low‑power post‑DAC filtering and anti‑aliasing applications.
The devices are offered in an 8‑Pin uMAX package and provide several filter responses (Elliptic, Bessel, Butterworth) with corner frequencies from 1 Hz to 45 kHz. Detailed electrical characteristics, typical operating curves, harmonic distortion data, and ordering information are included in the document.
