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.
THERMAL RESISTANCE
Thermal impedance can be lowered to 23°C/W by soldering the
exposed package pad to an external heat sink (for example, the
internal PCB copper ground plane). However, this is not necessary
for the power dissipation and operating temperature range of
the AD9726.
