Description
The D61 Series of small 4-pole fixed-frequency, precision active filters provide high performance linear active filtering in a compact 32-pin DIP package, with a broad range of corner frequencies and a choice of transfer functions. Individual D61 filters can serve in low-pass or high- pass applications or be combined to create custom band-pass or band reject filters. These fully self- contained units require no external components or adjustments. Each model comes factory tuned to a user-specified corner frequency between 0.02 Hz and 1.00 Hz and operate with low total harmonic distortion over a wide dynamic input voltage range from non-critical +/-5V to +/-18V power supplies.
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 Acoustic and vibration analysis and control Noise elimination Signal reconstruction Features/Benefits: Low harmonic distortion and wide signal-to-noise ratio Compact 1.8"L x 0.8"W x 0.5"H minimizes board space requirements. Plug-in ready-to-use, reducing engineering design and manufacturing cycle time. Factory tuned, no external clocks or adjustments needed Broad range of transfer characteristics and corner frequencies to meet a wide range of applications.
