D64BP Series Fixed Frequency 2-Pole Pair Filters Band Pass Description: The D64BP Series of small 2-pole-pair fixedfrequency, precision band-pass active filter that provides 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, band-pass D64BP filters pass all frequencies lying between the upper and lower -3dB points of the amplitude response curve. Available Q’s for D64BP models are 1, 2, 5, or 10. Features/Benefits: • Compact 1.8"L x 0.8"W x 0.3"H 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.
