D74 & DP74 Series
1.0 Hz to 100 kHz
Fixed Frequency
Description
The D74 and DP74 Series of low-power, fixed-
frequency, linear active filters are high performance,
4-pole filters in a compact package. These
Butterworth and Bessel low-pass and Butterworth
high-pass filters (D74 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 (DP74, 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 鹵5V to 鹵18V power
supplies.
Features/Benefits:
鈥?Low cost solution for low frequency signal
conditioning
鈥?Compact DIP design minimizes board space
requirements
鈥?Plug-in ready-to-use, reducing engineering design
and manufacturing time
鈥?Factory tuned, no external clocks or adjustments
needed saving time and labor of other discrete
assembly solutions
鈥?Low harmonic distortion and wide signal-to-noise
ratio to 12 bit resolution
Applications
鈥?Anti-alias filtering
鈥?Vibration & shock analysis
鈥?Automatic test equipment
鈥?Aerospace, navigation and sonar
鈥?Communication systems
鈥?Medical electronics
鈥?Sound and vibration testing
鈥?Noise elimination
鈥?Process control
