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 currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specified.
Note 3: Limits on maximum rating is defined as whichever limit occurs first.
An internal clamp limits the GATE pin to a minimum of 10V above source.
Driving this pin to voltages beyond the clamp may damage the device.
Note 4: Guaranteed by design and not subject to test.
Note 5: Integral nonlinearity is defined as the deviation of a code from a
precise analog input voltage. Maximum specifications are limited by the
LSB step size and the single shot measurement. Typical specifications are
measured from the 1/4, 1/2 and 3/4 areas of the quantization band.
Note 6: For the V
DD
-SENSE channel, full-scale is at code 255 but codes
above 200 may be discarded by offset cancellation. Full scale error and
total unadjusted error are evaluated over the 0-200 code range. Full scale
voltage corresponds to the theoretical code 255, and is extrapolated from
a code 200 measurement.
