Description:
The 824BP Series is a 2-pole-pair digitally
programmable precision band-pass active filter that
provides high performance in a compact 2" x 2"
footprint. 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. 824BP 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 824BP filters pass all frequencies lying
between the upper and lower -3dB points of the
amplitude response curve. Available Q’s for 824BP
models are 1, 2, 5, or 10.
