Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to GND with GND and OGND
shorted (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above V
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above V
Note 4: When these pin voltages are taken below GND they will be
clamped by internal diodes. When these pin voltages are taken above V
they will not be clamped by internal diodes. This product can handle input
currents of greater than 100mA below GND without latchup.

Note 6: Integral nonlinearity is defi ned as the deviation of a code from a
best fi t straight line to the transfer curve. The deviation is measured from
the center of the quantization band.
Note 7: Offset error is the offset voltage measured from –0.5 LSB when
the output code fl ickers between 00 0000 0000 0000 and 11 1111 1111
