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.
Note 3: When these pin voltages are taken below V
mode) or above V
can handle input currents greater than 60mA without latch-up if the pin is
driven below V
Note 4: When these pin voltages are taken below V
mode), they will be clamped by internal diodes. This product can handle
input currents greater than 60mA without latch-up if the pin is driven
below V
Note 5: Guaranteed by design, not subject to test.

Note 6: Linearity, offset and full-scale specifications apply for unipolar and
bipolar modes.
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: The rising edge of CONV starts a conversion. If CONV returns low
at a bit decision point during the conversion, it can create small errors. For
best performance, ensure that CONV returns low either within 100ns after
the conversion starts (i.e., before the first bit decision) or after the 14
clock cycles. (Figure 13 Timing Diagram).
Note 10: If this timing specification is not met, the device may not respond
to a request for a conversion. To recover from this condition a NAP
request is required.
