Test Conditions/Comments
Measured at T
Measured at T
Using ADCREF, measured at T
At any gain settings
Differential voltage increase on the attenuator
when the current source is on, over a range of
T
Direct path to ground
20 kΩ resistor selected
Allowed continuous current through the switch
with direct path to ground
