428 Series

10 Hz - 102.4 kHz

4-Bit Programmable

Description

The 428 Series are 8-pole digitally programmable

low-pass and high-pass active filters. These new

filters take advantage of the company鈥檚 proprietary

designs using surface-mount technology to provide

a low profile, compact package in minimal board

space. 428 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 428 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 鹵12V to 鹵18V power supplies.

Features/Benefits:

鈥?Low harmonic distortion and wide signal-to-noise

ratio to 16-bit resolution.

鈥?Compact 1.8"L x 0.8"W x 0.3"H min. (32-pin DIP

footprint) minimizes board space requirements.

鈥?Digitally programmable corner frequency allows

selecting cut-off frequencies specific to each

application.

鈥?Plug-in ready-to-use, reducing engineering design

and manufacturing cycle time.

鈥?Factory tuned, no external clocks or adjustments

needed.

鈥?Broad range of transfer characteristics and corner

frequencies to meet a wide range of applications.

Applications

鈥?Anti-alias filtering

鈥?Data acquisition systems

鈥?Communication systems and electronics

鈥?Medical electronics equipment and research

鈥?Aerospace, navigation and sonar applications

鈥?Acoustic and vibration analysis and control

鈥?Real and compressed time data analysis

鈥?Noise elimination

鈥?Signal reconstruction
