Maximum Power Dissipation
The maximum safe power dissipation for the ADA4310-1 is
limited by the associated rise in junction temperature (T
J
) on
the die. At approximately 150C, which is the glass transition
temperature, the plastic changes its properties. Even temporarily
exceeding this temperature limit can change the stresses that the
package exerts on the die, permanently shifting the parametric
performance of the amplifiers. Exceeding a junction temperature of
150°C for an extended period can result in changes in silicon
devices, potentially causing degradation or loss of functionality.
Figure 4 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 10-lead MINI_SO_EP
(44°C/W) and for the 16-lead LFCSP (63°C/W) on a JEDEC
standard 4-layer board. θ
