D70 Series
100 Hz to 50 kHz Fixed Frequency
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 saving of the dual in-line package (DIP). Each model comes factory tuned to a user-specified corner frequency between 100Hz and 50kHz. These fully self-contained units require no external components 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 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 · Real and compressed time data analysis · Noise elimination · Signal reconstruction
