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 -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 to 100 kHz and operate with low harmonic distortion over an input voltage range ±10 V. Available Low-Pass Models: D100L4L 4-Pole Bessel D100L4B 4-Pole Butterworth D100L8L 8-Pole Bessel D100L8B 8-Pole Butterworth General Specifications Pin-out/package data & order information Page

Notes: 1. Input and output signal voltage referenced to supply common. 2. Output is short circuit protected to common. DO NOT CONNECT TO ±Vs. 3. Adjustable to zero. 4. Units operate with or without offset pin connected. 5. How to specify Corner Frequency. Corner frequency is specified by attaching a three-digit frequency designator to the basic model number. Corner frequencies can range from to 100 kHz.
