R854 Series

2" x 4" Range Switch

4-Pole Filters

1.0 Hz to 102.4 kHz

8-Bit Programmable

Description

The R854 Series are digitally programmable, 4-pole

low-pass and high-pass active filters that contain a

low and a high programmable frequency range, with

each range tunable over a 256:1 ratio. R854 filters

are available with any two 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 that can be operated in a transparent or

latching mode and 1 logic input for range selection.

All R854 Series models are convenient, easy to use

fully finished filters which require no external

components or adjustments. They feature low

harmonic distortion, and precision phase and

amplitude characteristics. R854 filters operate from

non-critical ±12 to ±18 Vdc power supplies, have a

10 kΩ (min.) input impedance, a 10 Ω (max.) output

impedance.

Features/Benefits:

• 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.
