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.
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.
models are 1, 2, 5, or 10 and D68BR filters are 3 or
10.
Features/Benefits:
• Compact 32-pin footprint minimizes board space
• Plug-in ready-to-use, reducing engineering design
• Factory tuned, no external clocks or adjustments
• Broad range of center frequencies to meet a wide
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
