General Description
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 fre-
quencies from 1Hz to 12kHz, making them ideal for
low-power post-DAC filtering and anti-aliasing applica-
tions. They can be put into a low-power mode, reducing
supply current to 0.2A.
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.
