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.

Unit to unit match for the same transfer function, set to the same frequency and operating configuration, and from the same manufacturing lot. Use I/O jumpers to bypass input and output buffers, for low noise operation. With FMA, D100 distortion specs at 50k to 100kHz may degrade slightly. 2 1784 Chessie Lane, Ottawa, IL 61350 • Tel: 800/252-7074, 815/434-7800 • FAX: 815/434-8176 e-mail: [email protected] • Web Address: http://www.freqdev.com D100L Series Specifications Pin-Out and Package Data Ordering Information (25ºC and Vs ± 15 Vdc) 0.80"(max) FO <10 kHz 1.0 kΩ min. ±10 Vpeak ± Vs 0.30"(max) 0.15" (min) 0.025" (dia) 1k Ω min. ± 5V ± 10V 10 mA max. 2 mV typ. 20 mV max. 50 µV/ºC.
