D68BP & D68BR Series

Band Pass and Band Reject

Description:

The D68BP and D68BR Series of small 4-pole-pair

fixed-frequency, precision band-pass and band-

reject (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.

Applications

• Power line interference rejection

• Transducer output filtering

• Production test instrumentation

• Medical electronics equipment and research

• Comb filtering and equalization

• Noise and harmonic analysis

• RMS measurements

• Frequency spectrum analysis

Notes:

- Vs

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.
