D68BP & D68BR Series Fixed Frequency 4-Pole Pair Filters Band Pass and Band Reject 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 1 Hz to 100 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 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 1, 2, 5, or 10 and D68BR filters are 3 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.
