| D76 & DP76 Series 1.0 Hz to 100 kHz Fixed Frequency Description The D76 and DP76 Series of low-power, fixedfrequency, linear active filters are high performance, 6-pole filters in a compact package. These Butterworth and Bessel low-pass and Butterworth high-pass filters (D76 only) combine linear active filter design with the space savings of a 32-pin dual in-line package (DIP). Each model comes factory tuned to a user-specified corner frequency between 1 Hz and 100 kHz (DP76, 1 Hz to 5kHz). These fully self-contained units require no external components or adjustments and operate with dynamic input voltage range from non-critical 5V to 18V power supplies. Features/Benefits: * Low cost solution for low frequency signal conditioning * Compact DIP design minimizes board space requirements * Plug-in ready-to-use, reducing engineering design and manufacturing time * Factory tuned, no external clocks or adjustments needed saving time and labor of other discrete assembly solutions * Low harmonic distortion and wide signal-to-noise ratio to 12 bit resolution Applications * Anti-alias filtering * Vibration & shock analysis * Automatic test equipment * Aerospace, navigation and sonar * Communication systems * Medical electronics * Sound and vibration testing * Noise elimination * Process control 1 32 Pin DIP 6-Pole Filters Available D76L6B DP76L6B D76L6L DP76L6L Low-Pass Models: . . . . . . . . . . . . . . . . 6-pole Butterworth . . . . . . . . . . . . . . .2 6-pole Butterworth (Low Power) . . . . .2 6-pole Bessel . . . . . . . . . . . . . . . . . . .2 6-pole Bessel (Low Power) . . . . . . . .2 Available High-Pass Models: D76H6B 6-pole Butterworth . . . . . . . . . . . . . . .2 General Specifications: Pin-out/package data & ordering information . . . .3 25 Locust St, Haverhill, Massachusetts 01830 * Tel: 800/252-7074, 978/374-0761 * FAX: 978/521-1839 e-mail: sales@freqdev.com * Web Address: http://www.freqdev.com D76 & DP76 Series Fixed Frequency Model Product Specifications Transfer Function D76L6B & DP76L6B Low-Pass 6-Pole, Butterworth Low-Pass 6-Pole, Bessel 1.8" x 0.8" x 0.5" 1.8" x 0.8" x 0.3" 1.8" x 0.8" x 0.5" 1 Hz to 100 kHz 1 Hz to 5 kHz Appendix A Page 3 0.0 dB 0 0.1 dB typ.
