Description

The 854 Series are digitally programmable low-pass and high-pass active filters that are tunable over a 256:1 frequency range. 854 filters are available with any one of six standard factory-set tuning ranges up to 102.4 kHz. These units contain 8 CMOS logic inputs that can be operated in a transparent or latching mode.

All 854 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. 854 filters operate from non-critical ±12 to ±18 Vdc power supplies, have a 10 k (min.) input impedance, a 10 (max.) output impedance and offer dc voltage offset adjustment.
