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