MAX296EWE

The MAX7480 8th-order, lowpass, Butterworth,

switched-capacitor filter (SCF) operates from a single

+5V supply. The device draws only 2.9mA of supply

current and allows corner frequencies from 1Hz to

2kHz, making it ideal for low-power post-DAC filtering

and anti-aliasing applications. The MAX7480 features a

shutdown mode, which reduces the supply current to

0.2?A.

Two clocking options are available: 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 MAX7480 Butterworth filter provides a maximally

flat passband response. The fixed response simplifies

the design task to selecting a clock frequency.
