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:

Programmable Filters Modules
818, 824, 828, 828BP, 828BR, 854, 858, R854, R858
I. Scope
The following precautions are necessary when handling and installing Frequency Devices
programmable filter modules.
II. Digital Circuit Description
The digital input pins connect directly to 4000 series CMOS logic, such as the 4053 analog switch. The
power supply (Vss) for the digital logic on the module comes directly from the +15 Volt pin on the
module. This sets the threshold voltage at 11.0 V minimum to 15.0 V maximum for a "1" (High) level
and 0.0 V minimum to 4.0 V maximum for a "0" (Low) level. Applying a voltage between 4.0 and 11.0
V will produce unpredictable operation. Connecting 5 Volt or 3.3 V logic devices directly to the filter
module without using a voltage translator will result in erratic operation of the filter.
III. (VERY IMPORTANT) Power-Up and Power-Down Sequence
Do not plug-in or un-plug module while power is applied.
It is imperative that power is
supplied to the + 15 V pin on the filter module before or at the same instance that any digital pin is
pulled High (> 0.0 V). Failure to do this will result in excessive current flowing through the digital input
pin and through a protection diode internal to the 4000 logic, which will result in damage to the module.
The proper power-up and power-down sequence is:
1. Connect filter module ground.
2. Connect filter module +15 V.
3. Connect filter module -15 V.
4. Connect the input signal.
All four of the above steps can also occur simultaneously. Power-down should occur in the reverse
order.
IV. ESD Issues
Like most modern electronic equipment, the modules can be damaged by electrostatic discharge (ESD).
The modules are shipped from the factory in sealed, anti-static packaging and should be kept in the
sealed package prior to mounting on a circuit board. The following additional rules should also be
observed when handling the modules after they are removed from the factory packaging:
1. Only a person wearing a properly grounded wrist strap should handle the modules.
2. Any work surface that the modules are placed on must be properly ESD grounded.
3. Any insulating materials capable of generating static charge (such as paper) should be kept
away from the modules.
Static generating clothing should be covered with an ESD-protective smock.
