D64BP Series
Band Pass
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.
Fixed Frequency
2-Pole Pair Filters
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.
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:
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 Hz to 100 kHz.
