D72 & DP72 Series
1.0 Hz to 100 kHz Fixed Frequency
Description The D72 and DP72 Series of low-power, fixedfrequency, linear active filters are high performance, 2-pole filters in a compact package. These Butterworth and Bessel low-pass and Butterworth high-pass filters (D72 only) combine linear active filter design with the space savings of a 16-pin dual in-line package (DIP). Each model comes factory tuned to a user-specified corner frequency between 1 Hz and 100 kHz (DP72, 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 Available D72L2B DP72L2B D72L2L DP72L2L Low-Pass Models: . . . . . . . . . . . . . . . . 2-pole Butterworth . . . . . . . . . . . . . . .2 2-pole Butterworth (Low Power) . . . . .2 2-pole Bessel . . . . . . . . . . . . . . . . . . .2 2-pole Bessel (Low Power) . . . . . . . .2
