D64 & DP64 Series
32-Pin DIP
4 - Pole Filters
1.0 Hz to 100 kHZ
Fixed Frequency
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.
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.
