8-Pole Filters
Description
The 428 Series are 8-pole digitally programmable
low-pass and high-pass active filters. These new
filters take advantage of the company’s proprietary
designs using surface-mount technology to provide
a low profile, compact package in minimal board
space. 428 filters are factory tuned to one of ten
preset 4-bit binary ranges from 10 Hz to 102.4 kHz.
Contact the factory for custom discrete tuning
ranges, maximum span 1000:1.
All 428 Series models are easy to use fully finished
filters which require no external components or
adjustment. They feature low harmonic distortion,
near theoretical phase and amplitude characteristics
and operate over a dynamic input voltage range
from non-critical 12V 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 min. (32-pin DIP
footprint) minimizes board space requirements.
• Digitally programmable corner frequency allows
selecting cut-off frequencies specific to each
application.
• Plug-in ready-to-use, reducing engineering design
and manufacturing cycle time.

1.Normalized Group Delay:
The above delay data is normalized to a corner frequency
of 1.0Hz.The actual delay is the normalized delay divided
by the actual corner frequency (fc).
Normalized Delay
Actual Delay =
Actual Corner Frequency (fc) in Hz
