428L4E General Description


The 428 Series are 8-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. 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 ±12V to ±18V power supplies.

428L4E Features

• 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.

428L4E Typical Application

• 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
