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.
