Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2:
Operating Ratings indicate conditions for which the device is functional. These ratings do not guarantee specific performance limits. For guaranteed speci-
fications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance character-
istics may degrade when the device is not operated under the listed test conditions.
Note 3:
All voltages are measured with respect to AGND = DGND = 0 V
DC
, unless otherwise specified.
Note 4:
When the input voltage V
IN
at any pin exceeds the power supplies (V
IN
<
(AGND or DGND) or V
IN
>
V
CC
) the current at that pin should be limited to 5 mA.
The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four pins.
Note 5:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
,
θ
JA
and the ambient temperature, T
A
. The maximum
allowable power dissipation at any temperature is P
D
= (T

)/
