5BAF Series
6-Pole
Description
Differential
Low-Pass Filters
The 5BAF Series are differential-input 6-Pole
Butterworth or Bessel low-pass anti-alias 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 frequency from 1 Hz to 50 kHz. These filters
are ideally suited to sharply limit A/D converter
bandwidth to eliminate aliasing higher frequency
input 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 74 dB (min.) at 1
kHz. A self contained dc-to-dc converter enables the
5BAF filters to operate from a non-critical +5 鹵10%
volt power source key in many systems since +5V
logic power is readily available.
Features/Benefits:
鈥?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
鈥?5BAF modules allow for partitioning between sys-
tem segments providing a means to minimize
ground loops
鈥?Factory tuned, no external clocks or adjustments
needed
鈥?5B plug-in compatible provides quick and easy in-
stallation
鈥?Broad range of corner frequencies to meet a wide
range of applications
Applications
鈥?Anti-alias filtering
鈥?Vibration analysis
鈥?Industrial and process control
鈥?Noise reduction
鈥?Signal reduction
鈥?Test systems
