ETC D72L2B

D72 & DP72 Series
1.0 Hz to 100 kHz
Fixed Frequency
16 Pin DIP
2-Pole Filters
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
