5BAF Series

Differential

6-Pole

Description

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 ±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
