818 Series
2" x 4"
8-Pole Filters
Description
The 818 Series are digitally programmable low-pass
and high-pass active filters that are tunable over a
256:1 frequency range. 818 filters are available with
any one of five standard factory-set tuning ranges or
8-bit custom ranges from 1 kHz to 1.28 MHz. These
units contain 8 CMOS logic inputs.
818 Series models are convenient, low profile, easy
to use fully finished filters which require no external
components or adjustments.
harmonic distortion, and near theoretical amplitude
characteristics. 818 filters operate from non-critical
±12 to ±18 Vdc power supplies, have a 5 k
(min.)
input impedance, a 10
(max.) output impedance
and low-pass models offer dc voltage offset
adjustment.
They feature low
Features/Benefits:
Low harmonic distortion and wide signal-to-noise
ratio to 12-bit resolution
Digitally programmable corner frequency allows
selecting cut-off frequencies specific to each
application
Plug-in ready-to-use, reducing engineering design
and manufacturing cycle time
Factory-set tuning range, no external clocks or
adjustments needed
Broad range of transfer characteristics and corner
frequencies to meet a wide range of applications
Applications
Anti-alias and band-pass filtering
Data acquisition systems
Satellite and telecommunications
Acoustic and vibration analysis and control
Aerospace, navigation and sonar
Medical research and electronic equipment
Engine test and simulation
Noise elimination
Video systems
Signal reconstruction
