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).

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.
