D68 & DP68 Series
1.0 Hz to 100 kHz Fixed Frequency
Description The D68 and DP68 Series of small 8-pole fixedfrequency, precision active filters provide high performance linear active filtering in a compact 32pin DIP package, with a broad range of corner frequencies and a choice of transfer functions. Individual D68 filters can serve in low-pass or highpass applications (DP68, low-pass only) or be combined to create custom band-pass or bandreject filters. These fully self-contained units require no external components or adjustments. Each model comes factory tuned to a user-specified corner frequency between 1 Hz and 100 kHz (DP68, 1 Hz to 5 kHz) and operate with low total harmonic distortion over a wide dynamic input voltage range from non-critical +/-5V to +/-18V power supplies. Features/Benefits: * Low harmonic distortion and wide signal-to-noise ratio to 16 bit resolution. * Compact 1.8"L x 0.8"W x 0.3"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. 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 Available Low-Pass Models: . . . . . . . . . . .Page D68L8B & DP68L8B 8-pole Butterworth . . . . . . . . . . . . . . . . .2 D68L8E & DP68L8E 8-pole, 6 zero elliptic, 1.77 (-80dB) . . . .2 D68L8EX & DP68L8EX 8-pole, 6 zero elliptic, 1.56 (-80dB) . . . .2 D68L8EY & DP68L8EY 8-pole, 6 zero elliptic, 2.00 (-100dB) . . .2 D68L8L & DP68L8L 8-pole Bessel. . . . . . . . . . . . . . . . . . . . .3 D68L8D60 & DP68L8D60 8-pole constant delay (-60 dB) . . . . . . . .3 D68L8D & DP68L8D 8-pole constant delay (-80 dB) . . . . . . . .3 D68L8D10 & DP68L8D10 8-pole constant delay (-100 dB) . . . . . . .3 Available High-Pass Models: . . . . . . . . . . . . . . . .
