Fixed Frequency
D01 Series
32-Pin DIP
8-, 6-, 4-Pole Filters
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 non-
critical 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
