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).

by internal diodes. This product can handle input currents greater than

latchup.

otherwise specified.

Note 6: Dynamic specifications are guaranteed for dual supply operation

dynamic specifications, refer to the Typical Performance Characteristics.

Note 7: 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 8: Bipolar offset is the offset voltage measured from –0.5LSB

when the output code flickers between 0000 0000 0000 and

1111 1111 1111.

Note 9: Guaranteed by design, not subject to test.

Note 10: Recommended operating conditions.
