MAX7411
MAX7411 is Switched-Capacitor Filters manufactured by Maxim Integrated.
- Part of the MAX7411-MAX7408 comparator family.
- Part of the MAX7411-MAX7408 comparator family.
Description
The MAX7408/MAX7411/MAX7412/MAX7415 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7408/MAX7411) or +3V (MAX7412/MAX7415) supply. The devices draw only 1.2m A of supply current and allow corner frequencies from 1Hz to 15k Hz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. They can be put into a low-power mode, reducing supply current to 0.2µA.
Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff-frequency control. An offset-adjust pin allows for adjustment of the DC output level.
The MAX7408/MAX7412 deliver 53d B of stopband rejection and a sharp rolloff with a transition ratio of 1.6. The MAX7411/MAX7415 achieve a sharper rolloff with a transition ratio of 1.25 while still providing 37d B of...
