Description
The D72 and DP72 Series of low-power, fixed-
frequency, 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.
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
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
