8-, 6-, 4-Pole Filters
Description
The D70 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 and Butterworth high-pass filters combine the excellent performance of linear multi-pole filter design with the space sav- ing of the dual in-line package (DIP). Each model comes factory tuned to a user-specified corner fre- quency between 100Hz and 50kHz. These fully self-contained units require no external compo- nents or adjustments. They operate with dynamic input voltage range from non-critical ±5V to ±18V power supplies. Features/Benefits: 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 Low harmonic distortion and wide signal-to-noise ratio to 14 bit resolution Broad range of pole configurations and corner fre- quencies to meet a wide range of applications
