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.     Applications Vibration analysis Industrial and process control Noise reduction Signal reduction Test systems Available Low-Pass Models: 5BAF-LPBE8 8-pole Bessel 5BAF-LPBU8 8-pole Butterworth 5BAF-LPBE6 6-pole Bessel 5BAF-LPBU6 6-pole Butterworth 5BAF-LPBE4 4-pole Bessel 5BAF-LPBU4 4-pole Butterworth Available High-Pass Models: 5BAF-HPBU8 8-pole Butterworth 5BAF-HPBU6 6-pole Butterworth 5BAF-HPBU4 4-pole Butterworth Note:Contact factory for lower frequency,noise or distortion options. 5BAF Series Low-Pass Butterworth Fixed Frequency 1 Hz to 100 kHz Model 5BAF-LPBU8 5BAF-LPBU6 5BAF-LPBU4 Product Specifications Transfer Function Size Range fc 8-Pole, Butterworth Std. 5B 1.00 Hz to 100 kHz 6-Pole, Butterworth Std. 5B 1.00 Hz to 100 kHz 4-Pole, Butterworth Std. 5B 1.00 Hz to 100 kHz Theoretical Transfer Characteristics Click to view Click to view Click to view Passband Ripple (theoretical) 0.0 dB 0.0 dB 0.0 dB DC Voltage Gain (non-inverting) 0 ± 0.1 dB typ 0 ± 0.1 dB typ 0 ± 0.1 dB typ Differential Gain 1 ± 0.3% 1 ± 0.3% 1 ± 0.3% Stopband Attenuation Rate 48 dB/octave 36 dB/octave 24 dB/octave Accuracy fc ±2% max. ±2% max. ±2% max.
