Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational section of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
MAXIMUM POWER DISSIPATION
The maximum safe power dissipation in the AD8250 package is
limited by the associated rise in junction temperature (T
the die. The plastic encapsulating the die locally reaches the
junction temperature. At approximately 140°C, 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 AD8250. Exceeding
a junction temperature of 140°C for an extended period can
result in changes in silicon devices, potentially causing failure.

Current must be kept to less than 6 mA.
Temperature for specified performance is −40°C to +85°C. For performance

Airflow increases heat dissipation, effectively reducing θ
addition, more metal directly in contact with the package leads
from metal traces, through holes, ground, and power planes
reduces the θ
