Description

The 818 Series are digitally programmable low-pass and high-pass active filters that are tunable over a 256:1 frequency range. 818 Series 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 Series operate from non-critical ±12 to ±18 Vdc power supplies, have a 5 k (min.) input impedance, a 10 (max.) output impedance and low-pass models offer dc voltage offset adjustment.
