D01-EVR Series 32-Pin DIP 8-Pole Filter 25 Hz to 1.00 MHz Fixed Frequency Description The D01-EVR is a small, fixed-frequency , linear active DIP filter that provides high performance linear, multi-pole filtering in a compact package. These Butterworth and Bessel low-pass filters combine the excellent performance of linear multi-pole filter design with the space saving of the dual in-line package (DIP). Each filter comes factory tuned to a user-specified corner frequency between 25Hz and1 MHz. These fully self-contained units require no external components or adjustments. They operate with dynamic input voltage range from non-critical ±2.5V to ±7.5V power supplies. Features/Benefits: Low harmonic distortion and wide signal-to-noise ratio to 12 bit resolution 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 Broad range of pole configurations and corner frequencies to meet a wide range of applications Applications Anti-alias filtering Data acquisition systems V ideo systems Communication systems and electronics Medical electronics equipment and research Aerospace, navigation and sonar applications Sound and vibration testing Real and compressed time data analysis Noise elimination Signal reconstruction Available Low-Pass Models: D01L8B-EVR 8-pole Butterworth . . . . . . . . . . . .2 D01L8L-EVR 8-pole Bessel . . . . . . . . . . . . . . . .2 General Specifications: Pin-out/package data & ordering information 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 . . . .3 D01-E V R S eries 8-P ole Low-P as s F ilters F ixed F requency Model D01L8B-EVR D01L8L-EVR Transfer Function 8-Pole, Butterworth 8-Pole, Bessel Size 1.80" x 0.80" x 0.30" 1.80" x 0.80" x 0.30" Range fc 25 Hz to 1 MHz 25 Hz to 1 MHz Theoretical Transfer Characteristics Appendix A Page 9 Appendix A Page 4 Passband Ripple 0.0 dB 0.0 dB 0 ± 0.1 dB max. 0 ± 0.02 dB typ. 0 ± 0.1 dB max. 0 ± 0.02 dB typ.
