Electrical Characteristics Notes
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
Human body model; 100 pF discharge through a 1.5 k
X
resistor. All pins except pins 8 and 13 which are protected to 1000V and pins 1, 2, 18 and 19 which
are protected to 500V.
Note 3:
The maximum power dissipation is a function of T
,
i
JA
, and T
A
and is limited by thermal shutdown. The maximum allowable power dissipation at any
ambient temperature is P
D
e
(T

)/
i
JA
. If this dissipation is exceeded, the die temperature will rise above 150
§
C and the device will eventually go into
thermal shutdown. For the LMD18400 the junction-to-ambient thermal resistance,
i
JA
, is 60

Note 5:
All limits are 100% production tested at
