D100L Series

100 Hz to 100 kHz

Low Noise Fixed Frequency

4- and 8- Pole

Low-Pass Filters

Description:

D100L Series filters are low noise and distortion

4- and 8-pole, Butterworth or Bessel fixed

frequency low-pass filters. These filters feature

near

theoretical

low

noise

and

distortion

performance, by providing up to -120 dB noise

floors (20-Bit). D100L’s take advantage of FDI’s

design expertise utilizing high performance

amplifiers and surface-mount technology to

provide design engineers with precision signal

conditioning solutions in a compact package.

These fully self-contained units require no

external components or adjustments.

Each

D100L comes factory tuned to a user specified

corner frequency between 100 Hz to 100 kHz and

operate with low harmonic distortion over an input

voltage range to ±10 V.

Features/Benefits:

• Small 32-pin DIP (1.8"L x 0.8"W) footprint

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 corner frequencies to meet a

wide range of applications.

Applications

• Transducer output filtering:

• Production test instrumentation

• Medical electronics equipment and research

• Noise and harmonic analysis

• Frequency spectrum analysis
