D76 & DP76 Series 1.0 Hz to 100 kHz Fixed Frequency 32 Pin DIP 6-Pole Filters 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 Available D76L6B DP76L6B D76L6L DP76L6L Applications • Anti-alias filtering • Vibration & shock analysis • Automatic test equipment • Aerospace, navigation and sonar 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 • Communication systems • Medical electronics General Specifications: Pin-out/package data & ordering information . . . .3 • Sound and vibration testing • Noise elimination • Process control 1 1784 Chessie Lane, Ottawa, IL 61350 • Tel: 800/252-7074, 815/434-7800 • FAX: 815/434-8176 e-mail: [email protected] • Web Address: http://www.freqdev.com D76 & DP76 Series 6-Pole Low-Pass and High-Pass Filters Fixed Frequency Model D76L6B & DP76L6B D76L6L & DP76L6L Product Specifications Low-Pass Low-Pass Transfer Function 6-Pole, Butterworth 6-Pole, Bessel Model High-Pass Transfer Function Size D76 1.00 Hz to 1.00 kHz 1.8” x 0.8” x 0.5” D76 1.01 kHz to 100 kHz 1.8” x 0.8” x 0.3” DP761.00 Hz to 5.00 kHz 1.8” x 0.8” x 0.5” 1.8” x 0.8” x 0.5” 1.8” x 0.8” x 0.3” 1.8” x 0.8” x 0.5” Range fc D76 DP76 1 Hz to 100 kHz 1 Hz to 5 kHz 1 Hz to 100 kHz 1 Hz to 5 kHz Theoretical Transfer Characteristics Appendix A Page 8 Passband Ripple 0.0 dB Range fc D76 1 Hz to 100 kHz Appendix A Page 3 Theoretical Transfer Characteristics Appendix A Page 28 0.0 dB Passband Ripple 0.0 dB (theoretical) 0 ± 0.1 dB typ. 0 ± 0.1 dB typ.
