8th-Order, Lowpass, Bessel,
Switched-Capacitor Filters
General Description
The MAX7401/MAX7405 8th-order, lowpass, Bessel,
switched-capacitor filters (SCFs) operate from a single
+5V (MAX7401) or +3V (MAX7405) supply. These
devices draw only 2mA of supply current and allow cor-
ner frequencies from 1Hz to 5kHz, making them ideal
for low-power post-DAC filtering and anti-aliasing appli-
cations. They feature a shutdown mode that reduces
supply current to 0.2µA.
Two clocking options are available on these devices:
self-clocking (through the use of an external capacitor)
or external clocking for tighter corner-frequency control.
An offset adjust pin allows for adjustment of the DC out-
put level.
The MAX7401/MAX7405 Bessel filters provide low over-
shoot and fast settling. Their fixed response simplifies
the design task to selecting a clock frequency.
