Description

The D64 and DP64 Series of small 4-pole fixed-frequency, precision active filters provide high performance linear active filtering in a compact 32-pin DIP package, with a broad range of corner frequencies and a choice of transfer functions. Individual D64 filters can serve in low-pass or high-pass applications (DP64, low-pass only) or be combined to create custom band-pass or band-reject filters. These fully self-contained units require no external components or adjustments. Each model comes factory tuned to a user-specified corner frequency between 1 Hz and 100 kHz (DP64, 1 Hz to 5 kHz) and operate with low total harmonic distortion over a wide dynamic input voltage range from non-critical +/-5V to +/-18V power supplies.

Features/Benefits:

  • Low harmonic distortion and wide signal–to–noise ratio
  • Compact 1.8"L x 0.8"W x 0.3"H minimizes board space requirements.
  • 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
  • Sound and vibration testing
  • Acoustic and vibration analysis and control
  • Noise elimination
  • Signal reconstruction
