Description

The D66 and DP66 Series of small 6-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 D66 filters can serve in low-pass or high-pass applications (DP66, 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 (DP66, 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 to 16 bit resolution
  • 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

 

Available High-Pass Models:

D66H6B
6-pole Butterworth
