MAX7427CUA+ by Analog Devices

5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters


The MAX7426/MAX7427 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7426) or +3V (MAX7427) supply. The devices draw only 0.8mA of supply current and allow corner frequencies from 1Hz to 12kHz, 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 MAX7426/MAX7427 deliver 37dB of stopband rejection and a sharp rolloff with a transition ratio of 1.25. Their fixed response limits the design task to selecting a clock frequency.
