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 828BP models are 1, 2, 5, or 10 and 828BR filters are 3 or 10.
