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:
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 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 3:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
,
i
JA
, and the ambient temperature, T
A
. The maximum
allowable power dissipation at any temperature is P

X
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 but not 100% tested. These limits are not used to calculate outgoing quality levels.
Note 8:
Non-linearity specifications are based on best straight line.
Note 9:
Guaranteed by design only.
Note 10:
Start conversion pulse duration greater than 3
(/2
clock periods will cause conversion errors.
