Description

The D76 and DP76 Series of low-power, fixed-frequency, linear active filters are high performance, 6-pole filters in a compact package. These Butterworth and Bessel low-pass and Butterworth high-pass filters (D76 only) combine linear active filter design with the space savings of a 32-pin dual in-line package (DIP). Each model comes factory tuned to a user-specified corner frequency between 1 Hz and 100 kHz (DP76, 1 Hz to 5kHz). These fully self-contained units require no external components or adjustments and operate with dynamic input voltage range from non-critical ±5V to ±18V power supplies.

Features/Benefits:

  • Low cost solution for low frequency signal conditioning
  • Compact DIP design minimizes board space requirements
  • Plug-in ready-to-use, reducing engineering design and manufacturing time
  • Factory tuned, no external clocks or adjustments needed saving time and labor of other discrete assembly solutions
  • Low harmonic distortion and wide signal-to-noise ratio to 12 bit resolution

 

Available High-Pass Models:

D76H6B 6-pole Butterworth
 

Applications

  • Anti-alias filtering
  • Vibration & shock analysis
  • Automatic test equipment
  • Aerospace, navigation and sonar
  • Communication systems
  • Medical electronics
  • Sound and vibration testing
  • Noise elimination
  • Process control
