MAX7410EUA

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

0.2?A.

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 output

level.

The MAX7409/MAX7413 Bessel filters provide low overshoot

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
