    D78 & DP78 Series  
    1.0 Hz to 100 kHz  
    Fixed Frequency  
    32 Pin DIP  
    8-Pole Filters  
    Description  
    The D78 and DP78 Series of low-power, fixed-  
    frequency, linear active filters are high performance,  
    8-pole filters in a compact package. These  
    Butterworth and Bessel low-pass and Butterworth  
    high-pass filters (D78 only) combine linear active  
    filter design with the space savings of a 32-pin dual  
    in-line package (DIP). Each model comes factory  
    tuned to a user-specified corner frequency between  
    1 Hz and 100 kHz (DP78, 1 Hz to 5kHz). These fully  
    self-contained units require no external components  
    or adjustments and operate with dynamic input  
    voltage range from non-critical ±5V to ±18V power  
    supplies.  
    Features/Benefits:  
    • Low cost solution for low frequency signal  
    conditioning  
    • Compact DIP design minimizes board space  
    requirements  
    • Plug-in ready-to-use, reducing engineering design  
    and manufacturing time  
    • Factory tuned, no external clocks or adjustments  
    needed saving time and labor of other discrete  
    assembly solutions  
    • Low harmonic distortion and wide signal-to-noise  
    ratio to 12 bit resolution
