Description

The D100B Series are low noise and distortion 2-pole-pair, fixed center frequency (fo) band-pass filters. These filters feature near theoretical low noise and distortion performance, by providing up to -120 dB noise floors (20-Bit). D100B'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 D100B comes factory tuned to a user specified corner frequency between 100 Hz to 100 kHz. Available Q's for D100B models are 1, 2 or 5 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 center 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

1. Q - Quality Factor for band-pass and band-reject filters. Q = fO/(fH-fL),
fo = sq.rt.(fH x fL) = (fH x fL)1/2
2. Use I/O jumpers to bypass input and output buffers, for low noise operation. With FMA, D100B distortion specs at 50k to 100kHz may degrade slightly.
