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 2.0"L x 2.0"W 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.
Description:
The 828BP and 828BR Series are 4-pole-pair
digitally programmable band-pass and band-reject
(notch) active filters. These new filters take
advantage of the company’s proprietary designs
using surface-mount technology to provide a low
profile, compact package in minimal board space.
828BP and 828BR filters are factory tuned to one of
three factory set tuning ranges or 8-bit custom
ranges from 1 Hz to 25.6 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 center frequency,
band-pass 828BP filters pass all frequencies lying
between the upper and lower -3 dB points of the
amplitude response curve, while 828BR band-reject
(notch) filters sharply attenuate those frequencies
that are bound and defined by the bottom of the
notch. Available Q’s for 828BPmodels are 1, 2, 5, or
10 and 828BR filters are 3 or 10.
