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 noncritical 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 and corner frequencies to meet a wide range of applications Applications Anti-alias filtering Data acquisition systems Video 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 Available Low-Pass Models:
