Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
The full-scale input sense voltage and the maximum output may cause permanent damage to the device. Exposure to any Absolute current must be considered to achieve the specified performance. Maximum Rating condition for extended periods may affect device
Note 6:
Supply voltage and input common mode voltage are varied while reliability and lifetime. amplifier input offset voltage is monitored.
Note 2:
Input and output pins have ESD diodes connected to ground. The
Note 7:
The specified gain error does not include the effect of external SENSEHI and SENSELO pins have additional current handling capability resistors RIN and ROUT. Although gain error is only guaranteed between specified as SENSEHI, SENSELO Input Current. 12V and 60V, similar performance is expected for V+ < 12V, as well.

Supply current is specified with the comparator output high. When comparator to transition from high to low is specified. The input voltage the comparator output goes low the supply current will increase by 75µA which causes the comparator output to transition from low to high is typically. the magnitude of the difference between the specified threshold and the hysteresis.
