Note 4:
Guaranteed and 100% production tested.
Note 5:
Guaranteed (but not 100% production tested) over the operating temperature. These limits are not used to calculate outgoing quality levels.
Note 6:
Settling time for gain change is the switching time for gain change plus settling time (see section on Settling Time).
Note 7:
WR minimum high threshold voltage increases to 2.4V under the extreme conditions when all three digital inputs are simultaneously taken from 0V to 5V at
a slew rate of greater than 500V/
