    Note 1:
     Absolute Maximum Ratings are those values beyond which the life
    of a device may be impaired.
    Note 2:
     All voltage values are with respect to ground with GND and OGND
    wired together (unless otherwise noted).
    Note 3:
     When these pin voltages are taken below GND or above V
    DD
    , they
    will be clamped by internal diodes. This product can handle input currents
    of greater than 100mA below GND or above V
    DD
     without latchup.

     with differential
    drive, unless otherwise noted.
    Note 5:
     Integral nonlinearity is defined as the deviation of a code from a
    straight line passing through the actual endpoints of the transfer curve.
    The deviation is measured from the center of the quantization band.
    Note 6: 
    Offset error is the offset voltage measured from –0.5 LSB when
    the output code flickers between 00 0000 0000 0000 and
    11 1111 1111 1111.
    Note 7:
