Description

The D64 and DP64 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 D64 filters can serve in low-pass or high-

pass applications (DP64, low-pass only) 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 1 Hz and 100 kHz (DP64,

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.

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 0.3"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.
