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

Features/Benefits:

• Compact 1.8"L x 0.8"W x 0.3"H 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.

Description:

The D64BP Series of small 2-pole-pair fixed-

frequency, precision band-pass active filter that

provides 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, band-pass D64BP filters pass all

frequencies lying between the upper and lower -3dB

points of the amplitude response curve. Available

Q’s for D64BP models are 1, 2, 5, or 10.
