858 Series
0.1 Hz to 102.4 kHz
8-Bit Programmable
Description
2" x 4"
8-Pole Filters
The 858 Series are digitally programmable low pass
and high-pass active filters that are tunable over a
256:1 frequency range. 858 filters are available
with any one of six standard factory-set tuning
ranges up to 102.4 kHz. These units contain 8
CMOS logic inputs that can be operated in a
transparent or latching mode.
All 858 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. 858 filters operate
from non-critical ± 12 to ± 18 Vdc power supplies,
have a 10 kW (min.) input impedance, a 10
W
(max.)
output impedance and offer dc voltage offset
adjustment.
Features/Benefits:
Lower cost, high precision replacement for 848
and 878 series products.
• 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

How to use J-Flash Lite and J-Link BASE to burn the internal Flash of the STM32F107VC board?
Since J-Link BASE and J-Link EDU do not have the J-Flash software license, they cannot use the J-Flash software. Therefore, Segger has launched a simplified version of the J-Flash Lite software to fac...
