Power Dissipation
The LT1630/LT1631 amplifiers combine high speed and
large output current drive in a small package. Because the
amplifiers operate over a very wide supply range, it is
possible to exceed the maximum junction temperature of
150
°
C in plastic packages under certain conditions. Junc-
tion temperature T
J
is calculated from the ambient tem-
perature T
A
and power dissipation P
D
as follows:
LT1630CN8: T
J
= T

The power dissipation in the IC is the function of the supply
voltage, output voltage and load resistance. For a given
supply voltage, the worst-case power dissipation P
DMAX
occurs at the maximum supply current and when the
output voltage is at half of either supply voltage (or the
maximum swing if less than 1/2 supply voltage). There-
fore P
DMAX
is given by:
P

To ensure that the LT1630/LT1631 are used properly,
calculate the worst-case power dissipation, get the ther-
mal resistance for a chosen package and its maximum
junction temperature to derive the maximum ambient
temperature.
Example: An LT1630CS8 operating on
±
15V supplies and
driving a 500
, the worst-case power dissipation per
amplifier is given by:
P
DMAX
= (30V 4.75mA) + (15V – 7.5V)(7.5/500)
= 0.143 + 0.113 = 0.256W
If both amplifiers are loaded simultaneously, then the total
power dissipation is 0.512W. The SO-8 package has a
junction-to-ambient thermal resistance of 190
°
C/W in still
air. Therefore, the maximum ambient temperature that the
part is allowed to operate is:
T
A
= T

°
C/W)
T
A
= 150
°
C – (0.512W 190
°
C/W) = 53
°
C
For a higher operating temperature, lower the supply
voltage or use the DIP package part.
