D66 & DP66 Series
1.0 Hz to 100 kHz
Fixed Frequency
Description
The D66 and DP66 Series of small 6-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 D66 filters can serve in low-pass or high-
pass applications (DP66, 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 (DP66,
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
