    LT2078/LT2079
    Micropower, Dual and
    Quad, Single Supply,
    Precision Op Amps
    DESCRIPTIO
    N
    U
    The LT
    2078 is a micropower dual op amp in 8-pin small
    outline, standard surface mount package, and LT2079 is
    a micropower quad op amp offered in the standard 14-pin
    surface mount package. Both devices are optimized for
    single supply operation at 5V. 
    ±
    15V specifications are also
    provided.
    Micropower performance of competing devices is achieved
    at the expense of seriously degrading precision, noise,
    speed and output drive specifications. The design effort of
    the LT2078/LT2079 was concentrated on reducing sup-
    ply current without sacrificing other parameters. The
    offset voltage achieved is the lowest on any dual or quad
    nonchopper stabilized op amp––micropower or other-
    wise. Offset current, voltage and current noise, slew rate
    and gain bandwidth product are all two to ten times better
    than on previous micropower op amps.
    Both the LT2078/LT2079 can be operated from a single
    supply (as low as one lithium cell or two NiCd batteries).
    The input range goes below ground. The all NPN output
    stage swings to within a few millivolts of ground while
    sinking current––no power consuming pull-down resis-
    tors are needed. For applications requiring DIP packages
    refer to the LT1078/LT1079.
