Description

The 5BAF Series are differential-input low-pass and high-pass filters that are pin-out and package compatible with industry-standard 5B Series signal conditioning modules.Each filter comes factory tuned to user specified corner or center frequency
from 1 Hz to 100 kHz.These filters are ideally suited to sharply limit A/D converter bandwidth to eliminate unwanted signals and noise.

To serve real-world applications,all 5BAF Series filters are configured with a differential input having a common mode rejection ratio of <-70 dB (min.)at 1 kHz.A self contained dc-to-dc converter enables the 5BAF filters to operate from a non-critical +5,±10% volt power source,key in many systems since +5V logic power is readily available.

Features/Benefits:

  • The 10 volt input range with an overall gain of 1 provides an excellent match to both the transducer output and the data acquisition board input.
  • 5BAF modules allow for partitioning between system segments providing a means to minimize ground loops.
  • 5B plug-in compatible provides quick and easy insertion.
  • Factory tuned, no external clocks or adjustments needed.
  • Broad range of corner or center frequencies to meet a wide range of applications.
