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 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 6: Guaranteed by design, not subject to test.
Note 7: Linearity, offset and full-scale specifications apply for unipolar and
bipolar modes.
Note 8: 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 9: Bipolar offset is the offset voltage measured from – 0.5LSB when
the output code flickers between 0000 0000 0000 and 1111 1111 1111.
Note 10: 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).
