818 Series

2" x 4"

8-Pole Filters

1 kHz to 1.28 MHz

8-Bit Programmable

Description

The 818 Series are digitally programmable low-pass

and high-pass active filters that are tunable over a

256:1 frequency range. 818 filters are available with

any one of five standard factory-set tuning ranges or

8-bit custom ranges from 1 kHz to 1.28 MHz. These

units contain 8 CMOS logic inputs.

818 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 amplitude

characteristics. 818 filters operate from non-critical

12 to 18 Vdc power supplies, have a 5 kΩ (min.)

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

and low-pass models offer dc voltage offset

adjustment.

Features/Benefits:

• Low harmonic distortion and wide signal-to-noise

ratio to 12-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
