FREQUENCYDEVICES D70L6B

D70 Series
DIP Filters
8-, 6-, 4-Pole Filters
100 Hz to 50 kHz
Fixed Frequency
Description
The D70 Series of small, fixed-frequency, linear
active DIP filters provide high performance linear,
multi-pole filtering in a compact package, with a
broad range of pole configurations. These
Butterworth and Bessel low-pass and Butterworth
high-pass filters combine the excellent performance
of linear multi-pole filter design with the space saving of the dual in-line package (DIP). Each model
comes factory tuned to a user-specified corner frequency between 100Hz and 50kHz. These fully
self-contained units require no external components or adjustments. They operate with dynamic
input voltage range from non-critical ±5V to ±18V
power supplies.
Features/Benefits:
• 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
• Low harmonic distortion and wide signal-to-noise
ratio to 14 bit resolution
• Broad range of pole configurations and corner frequencies to meet a wide range of applications
Applications
• Anti-alias filtering
• Data acquisition 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
