Frequency D01L6B 32-pin dip 8-, 6-, 4-pole filter Datasheet

D01 Series
32-Pin DIP
8-, 6-, 4-Pole Filters
100 Hz to 1.00 MHz
Fixed Frequency
Description
The D01 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 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 1 MHz. These fully self-contained units require
no external components or adjustments. They
operate with dynamic input voltage range from noncritical ±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
• Video 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
