Note 1
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions
Note 2
All voltages are measured with respect to the ground pins
Note 3
When the input voltage (V
IN
) at any pin exceeds the power supply rails (V
IN
k
V
b
or V
IN
l
V
a
) the absolute value of the current at that pin should be
limited to 5 mA or less The 20 mA package input current limits the number of pins that can exceed the power supply boundaries with a 5 mA current limit to four
Note 4
Human body model 100 pF discharged through a 1 5 kX resistor
Note 5
Typicals are at 25 C and represent most likely parametric norm
Note 6
Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level)
Note 7
Design limits are guaranteed by not 100% tested These limits are not used to calculate outgoing quality levels
Note 8
Total unadjusted error includes offset full-scale linearity and multiplexer error
