D01 Series 100 Hz to 1.00 MHz Fixed Frequency 32-Pin DIP 8-, 6-, 4-Pole Filters 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 ±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 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: D01L8B 8-pole Butterworth D01L6B 6-pole Butterworth D01L4B 4-pole Butterworth D01L8L 8-pole Bessel . . . .
