D94 Series

1 Hz to 400 kHz*

Low Noise Fixed Frequency

4 - Pole Single Power Supply

Anti-Aliasing Low-Pass Filters

Description:

Applications

The D94 Series of small 4-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

•

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

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:

D94L4B

D94L4L

4-Pole Butterworth

4-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.
