1.0 Hz to 102.4 kHz
8-Bit Programmable
828 Series
2" x 2"
8-Pole Filters
Description
The 828 Series are digitally programmable low-pass
and high-pass active filters that are tunable over a
256:1 frequency range. 828 filters are available with
any one of five standard factory-set tuning ranges or
8-bit custom ranges from 1.0 Hz to 102.4 kHz.
These units contain 8 CMOS logic inputs.
All 828 Series models are convenient, low profile,
easy to use fully finished filters which require no
external components or adjustments. They feature
low harmonic distortion, and near theoretical phase
and amplitude characteristics. 828 filters operate
from non-critical 12 to 18 Vdc power supplies,
have a 10 k
(min.) input and a 10 (max.) output
impedance.
Features/Benefits:
Compact 2" x 2" design minimizes board space
requirements.
Low harmonic distortion and wide signal-to-noise
ratio to 16 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 filtering
Data acquisition 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

Digital Tuning Characteristics
The digital tuning interface circuits are a parallel set of eight
(8) 4053 CMOS switches which accept CMOS compatible
inputs for the eight tuning bits (D
0
- D
7
).
Filter tuning follows the tuning equation given below:
