D68HPLP Series 100 Hz to 100 kHz Band Pass Filter Fixed Frequency 4-Pole Pair Band Pass Filters Description: The D68HPLP Series of s mall 4-pole-pair f ixed frequency, precision band -pass active f ilters provide hi gh per formance i n a co mpact 32 -pin DIP pac kage, w ith a br oad r ange o f fixed ce nter frequencies (fo) from 1 Hz to 100 k Hz. Each filter type f eatures a nea r t heoretical am plitude/phase response along with low output voltage noise enabling these filters to achieve a 10,000:1 or better dynamic signal range. These filters consist o f a f our pol e Butterworth high pass filter followed by a four pole Bessel or Butterworth low pass filter i n one pack age. The user can select the low pass and high pass filter cutoff frequencies as long as they are not too close t o each ot her. The Q o f t his filter m ust remain below 1. For Qs of higher than 1 see our D68BP series of filters. See note 1 below to determine how to calculate the filter Q. Both f requencies are f actory pre-tuned t o within ±2% o f t he fixed, use r specified hi gh pass and low pass frequencies. B and pass D68HPLP filters pass all frequencies lying between t he upper and l ower -3dB points of t he a mplitude response curve.

Input and output signal voltage referenced to supply common. 2. Output is short circuit protected to common. DO NOT CONNECT TO ±Vs. 3. Adjustable to zero. 4. Units operate with or without offset pin connected. 5. How to specify Corner Frequency. Corner frequency is specified by attaching two three-digit frequency designators to the basic model number. The first number is the high pass corner frequency and the second number is the low pass corner frequency. Low Pass Corner Freq 5 e.g., 849 Hz 2.50 kHz 33.3 kHz Note: To order the Bessel Low-Pass filter use part number D68HPLPL We hope the information given here will be helpful.
