D68 & DP68 Series

1.0 Hz to 100 kHz

Fixed Frequency

32 Pin DIP

8-Pole Filters

Description

The D68 and DP68 Series of small 8-pole fixed-

frequency, precision active filters provide high

performance linear active filtering in a compact 32-

pin DIP package, with a broad range of corner

frequencies and a choice of transfer functions.

Individual D68 filters can serve in low-pass or high-

pass applications (DP68, low-pass only) or be

combined to create custom band-pass or band-

reject filters. These fully self-contained units

require no external components or adjustments.

Each model comes factory tuned to a user-specified

corner frequency between 1 Hz and 100 kHz (DP68,

1 Hz to 5 kHz) and operate with low total harmonic

distortion over a wide dynamic input voltage range

from non-critical +/-5V to +/-18V power supplies.

Features/Benefits:

• Low harmonic distortion and wide signal-to-noise
