4 - Pole Filters
Description
The D61 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 D61 filters can serve in low-pass or high-
pass applications 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 0.02 Hz
and 1.00 Hz 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 0.5"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.

Corner frequencies are specified by attaching a three digit frequency designator to the basic
model number. Corner frequencies can range from 0.02 Hz to 1.00 Hz.
