5BAF Series
Differential Fixed
Frequency Filters
Lowpass & Highpass
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 a 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 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.
