Description

The 824 Series are digitally programmable low pass and high pass active filters that are tunable over a 256:1 frequency range.  824 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 824 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.  824 filters operate from non-critical ± 12 to ± 18 Vdc power supplies, have a 10 kW(min.) input impedance, a 10 W(max.) output.
