TI I G CHARACTERISTICS
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
and AGND wired together unless otherwise noted.
Note 3: When these pin voltages are taken below V
will be clamped by internal diodes. This product can handle input currents
greater than 100mA below V
Note 4: When these pin voltages are taken below V
by internal diodes. This product can handle input currents greater than
100mA below V
Note 5: V
otherwise specified.
Note 6: Linearity, offset and full-scale specification apply for a single-
ended A
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: Typical RMS noise at the code transitions. See Figure 17 for
histogram.
Note 9: Bipolar offset is the offset voltage measured from – 0.5LSB when
the output code flickers between 0000 0000 0000 0000 and 1111 1111
1111 1111.
Note 10: Signal-to-Noise Ratio (SNR) is measured at 5kHz and distortion
is measured at 100kHz. These results are used to calculate Signal-to-Nosie
Plus Distortion (SINAD).
Note 11: Guaranteed by design, not subject to test.
Note 12: Recommended operating conditions.
Note 13: 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 performance ensure that CONVST returns high either within 250ns
after conversion start or after BUSY rises.
