FREQUENCYDEVICES D68BR4/10

D68BP & D68BR Series
Fixed Frequency
4-Pole Pair Filters
Band Pass and Band Reject
Description:
The D68BP and D68BR Series of small 4-pole-pair
fixed-frequency, precision band-pass and bandreject (notch) active filters that provide high
performance in a compact 32-pin DIP package, with
a broad range of fixed center frequencies (fo) from 1
Hz to 100 kHz. Each filter type features a near
theoretical amplitude/phase response along with low
output voltage noise enabling these filters to achieve
a 10,000:1 or better dynamic signal range.
Pretuned to within ±2% of the fixed, user specified
center frequency, D68BP band-pass filters pass all
frequencies lying between the upper and lower -3dB
points of the amplitude response curve, while D68BR
band-reject (notch) filters sharply attenuate those
frequencies that are bound and defined by the
bottom of the notch. Available Q’s for D68 BP
models are 1, 2, 5, or 10 and D68BR filters are 3 or
10.
Features/Benefits:
• Compact 32-pin footprint minimizes board space
requirements.
• Plug-in ready-to-use, reducing engineering design
and manufacturing cycle time.
• Factory tuned, no external clocks or adjustments
needed
• Broad range of center frequencies to meet a wide
range of applications.

1. 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 with out offset pin connected.
5. How to Specify Center Frequency:
Center frequencies are specified by attaching a three digit frequency
designator to the basic model number. Center frequencies can range from
1.00 Hz to 100 kHz.
