5th-Order, Lowpass,
Switched-Capacitor Filters
General Description
The MAX7409/MAX7410/MAX7413/MAX7414 5th-order,
lowpass, switched-capacitor filters (SCFs) operate from
a single +5V (MAX7409/MAX7410) or +3V (MAX7413/
MAX7414) supply. These devices draw only 1.2mA of
supply current and allow corner frequencies from 1Hz
to 15kHz, making them ideal for low-power post-DAC
filtering and anti-aliasing applications. They feature a
shutdown mode, which reduces the 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 MAX7409/MAX7413 Bessel filters provide low over-
shoot and fast settling, while the MAX7410/MAX7414
Butterworth filters provide a maximally flat passband
response. Their fixed response simplifies the design
task to selecting a clock frequency.
