D01 Series
100 Hz to 1.00 MHz 32-Pin DIP
Fixed Frequency 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
