ETC DP76H6L

D76 & DP76 Series
1.0 Hz to 100 kHz
Fixed Frequency
32 Pin DIP
6-Pole Filters
Description
The D76 and DP76 Series of low-power, fixedfrequency, linear active filters are high performance,
6-pole filters in a compact package. These
Butterworth and Bessel low-pass and Butterworth
high-pass filters (D76 only) combine linear active
filter design with the space savings of a 32-pin dual
in-line package (DIP). Each model comes factory
tuned to a user-specified corner frequency between
1 Hz and 100 kHz (DP76, 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 ±5V to ±18V power
supplies.
Features/Benefits:
• Low cost solution for low frequency signal
conditioning
• 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 saving time and labor of other discrete
assembly solutions
• Low harmonic distortion and wide signal-to-noise
ratio to 12 bit resolution
