D66 & DP66 Series 32 Pin DIP 6-Pole Filters 1.0 Hz to 100 kHz Fixed Frequency Description The D66 and DP66 Series of small 6-pole fixedfrequency, precision active filters provide high performance linear active filtering in a compact 32pin DIP package, with a broad range of corner frequencies and a choice of transfer functions. Individual D66 filters can serve in low-pass or highpass applications (DP66, low-pass only) or be combined to create custom band-pass or bandreject 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 (DP66, 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.
