Features, Applications 
Description The 424 Series are 4pole digitally programmable lowpass and highpass active filters. These new filters take advantage of the company's proprietary designs using surfacemount technology to provide a low profile, compact package in minimal board space. 424 filters are factory tuned to one of ten preset 4bit binary ranges from 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 noncritical to ±18V power supplies. Features/Benefits: Low harmonic distortion and wide signaltonoise ratio to 16bit resolution. Compact x 0.3"H min. (32pin DIP footprint) minimizes board space requirements. Digitally programmable corner frequency allows selecting cutoff frequencies specific to each application. Plugin readytouse, 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 Antialias 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 Programmable Specifications.
