D68 & DP68 Series

32 Pin DIP8-Pole Filters

Description

The D68 and DP68 Series of small 8-pole fixed-frequency, precision active filters provide high

performance linear active filtering in a compact 32-pin DIP package, with a broad range of cornerfrequencies and a choice of transfer functions.

Individual D68 filters can serve in low-pass or high-pass applications (DP68, low-pass only) or becombined 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 1 Hz and 100 kHz (DP68,1 Hz to 5 kHz) and operate with low total harmonic

distortion over a wide dynamic input voltage rangefrom non-critical +/-5V to +/-18V power supplies.

Features/Benefits:

Low harmonic distortion and wide signal-to-noiseratio to 16 bit resolution.

Compact 1.8"L x 0.8"W x 0.3"H minimizes boardspace requirements.

Plug-in ready-to-use, reducing engineering design

and manufacturing cycle time.

Factory tuned, no external clocks or adjustmentsneeded

Broad range of transfer characteristics and cornerfrequencies 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
