Description:
Applications
The D96 Series of small 6-pole fixed-frequency,
precision active filters provide high performance
linear active filtering in a compact package, with a
broad range of corner frequencies and a choice
of Butterworth or Bessel transfer functions. These
filters are designed to work with up to 16 Bit A/D
converters. 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 400
kHz* and operate with low total harmonic
distortion over a wide dynamic input voltage
range from non-critical single +5VDC to +18VDC
power supply. Each filter has a built in internal
+6VDC and -6VDC power supplies to power the
filter.
Signal reconstruction
Features/Benefits:
•
Low harmonic distortion and wide signal–
to–noise ratio to 16 bit resolution.
Available with Single or Differential inputs.
Available with DC coupled or AC coupled
inputs. (The AC corner frequency is a
single pole at 2 Hz.)
•
•
•
•
Compact 1.5"L x 2.0"W x 0.4"H minimizes
board space requirements.
Plug–in ready–to–use, reducing
engineering design and manufacturing
cycle time.
Available Low-Pass Models:
D96L6B
D96L6L
6-Pole Butterworth
6-Pole Bessel
•
•
Factory tuned, no external clocks or
adjustments needed.
Available in Butterworth or Bessel transfer
functions to meet a wide range of
applications.
•
•
Requires a single +5V to +18V power
supply to operate (The module generates
± 6 VDC internally to operate the filter).
One to one offset input that works with
your A/Ds reference output to set the
output of the filter in the center of your
A/Ds input range.
•
Available with built in gains from 0 dB to
60 dB.
