Description

The D01 Series of small, fixed-frequency, linear active DIP filters provide high performance linear, multi-pole filtering in a compact package, with a broad range of pole configurations. These Butterworth and Bessel low-pass filters combine the excellent performance of linear multi-pole filter design with the space saving of the dual in-line package (DIP). Each model comes factory tuned to a user-specified corner frequency between 100Hz and 1 MHz. These fully self-contained units require no external components or adjustments. They operate with dynamic input voltage range from non-critical ±2.5V to ±7.5V power supplies.

Features/Benefits:

  • Low harmonic distortion and wide signal-to-noise ratio to 12 bit resolution
  • 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
  • Broad range of pole configurations aner frequencies to meet a wide range of applications

 

 

Applications

  • Anti-alias filtering
  • Data acquisition systems
  • Video systems
  • Communication systems and electronics
