Notes for Electrical Characteristics
Note 1:
The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by T
JMAX
,
θ
JA
, and the ambient temperature,
T
A
. The maximum available power dissipation at any temperature is P
D
=(T
JMAX
−T
A
)/θ
JA
or the 25˚C P
dMAX
, whichever is less.
Note 2:
Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
Note 3:
Unless otherwise stated, these test conditions apply:
