D824 Series
1.0 Hz to 102.4 kHz
8-Bit Programmable
2" x 2"
Differential Input
4-Pole Filters
Description
The D824 Series are digitally programmable low
pass and high pass active filters with differential
input that are tunable over a 256:1 frequency range.
D824 filters are available with any one of five
standard factory-set tuning ranges up to 102.4 kHz.
These units contain 8 CMOS logic inputs .
All D824 Series models are convenient, low profile,
easy to use fully finished filters which require no ex-
ternal components or adjustments. They feature low
harmonic distortion, and near theoretical phase and
amplitude characteristics. D824 filters operate from
non-critical ± 12 to ± 18 Vdc power supplies, have a
10 kW (min.) input impedance, a 10 W (max.) output.
Features/Benefits:
⢠Compact 2" x 2" design minimizes board space
requirements.
⢠Digitally programmable corner frequency allows
selecting cut-off frequencies specific to each appli-
cation.
⢠Plug-in ready-to-use, reducing engineering de-
sign 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.
