RECOM ENDED OPERATING CONDITIONS
The q denotes specifications which apply over the operating temperature
range (0°C ≤ TA ≤ 70°C for commercial grade and – 40°C ≤ TA ≤ 85°C for
industrial grade).
Note 1: Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2: All voltage values are with respect to GND.
Note 3: Testing done at VCC = 5V, CLK = 250kHz and TA = 25°C unless
otherwise specified.
Note 4: Temperature integral nonlinearity is defined as the deviation of the
A/D code versus temperature curve from the best-fit straight line over the
device’s rated temperature range.
Note 5: Voltage integral nonlinearity is defined as the deviation of a code
from a straight line passing through the actual end points of the transfer
curve.
Note 6: Channel leakage current is measured after the channel selection.
Note 7: See guaranteed temperature limit curves vs temperature range on
the first page of this data sheet.
