Description

Features, Applications

Description: The D68BP and D68BR Series of small 4-pole-pair fixed-frequency, precision band-pass and bandreject (notch) active filters that provide high performance in a compact 32-pin DIP package, with a broad range of fixed center frequencies (fo) from to 100 kHz. Each filter type features a near theoretical amplitude/phase response along with low output voltage noise enabling these filters to achieve 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. Available Q's for D68 BP models are or 10 and D68BR filters are or 10. Features/Benefits: Compact 32-pin 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. 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
