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 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 DGND, OGND
Note 8: Bipolar offset is the offset voltage measured from –0.5LSB when
and AGND wired together unless otherwise noted.

Note 11: The falling CONVST edge starts a conversion. If CONVST returns
high at a critical point during the conversion it can create small errors. For
best results ensure that CONVST returns high either within 425ns after the
start of the conversion or after BUSY rises.

Note 12: Signal-to-noise ratio (SNR) is measured at 100kHz and distortion
is measured at 600kHz. These results are used to calculate signal-to-noise
plus distortion (SINAD).
Note 6: Linearity, offset and full-scale specifications apply for a single-
ended +A input with – A grounded.
