10 Hz to 102.4 kHz
4-Bit Programmable
424 Series
32-Pin DIP
4-Pole Filters
Description
The 424 Series are 4-pole digitally programmable
low-pass and high-pass active filters. These new
filters take advantage of the company’s proprietary
designs using surface-mount technology to provide
a low profile, compact package in minimal board
space. 424 filters are factory tuned to one of ten
preset 4-bit binary ranges from 10 Hz to 102.4 kHz.
Contact the factory for custom discrete tuning
ranges, maximum span 1000:1.
All 424 Series models are easy to use fully finished
filters which require no external components or
adjustment. They feature low harmonic distortion,
near theoretical phase and amplitude characteristics
and operate over a dynamic input voltage range
from non-critical ±12V to ±18V power supplies.
Features/Benefits:
Low harmonic distortion and wide signal-to-noise
ratio to 16-bit resolution.
Compact 1.8"L x 0.8"W x 0.3"H min. (32-pin DIP
footprint) minimizes board space requirements.
Digitally programmable corner frequency allows
selecting cut-off frequencies specific to each
application.
Plug-in ready-to-use, reducing engineering design
and manufacturing cycle time.
Factory tuned, no external clocks or adjustments
needed
Broad range of transfer characteristics and corner
frequencies to meet a wide range of applications.
Applications
Anti-alias filtering
Data acquisition systems
Communication systems and electronics
Medical electronics equipment and research
Aerospace, navigation and sonar applications
Acoustic and vibration analysis and control
Real and compressed time data analysis
Noise elimination
Signal reconstruction
