D68 & DP68 Series
32 Pin DIP
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 ratio to 16 bit resolution. Compact 1.8"L x 0.8"W x 0.3"H minimizes board space requirements. Plug-in ready-to-use, reducing engineering design and manufacturing cycle time. Factory tuned, no external clocks or adjustments needed Broad range of transfer characteristics and corner frequencies to meet a wide range of applications.
