Specification is for device in free air (TA = 25°C). 100-lead plastic LQFP (ST):

θJA = 40°C/W.

Maximum reflow temperatures are to JEDEC industry standard J-STD-020.

Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD8114/AD8115 is limited by the associated rise in junction

temperature. The maximum safe junction temperature for

plastic encapsulated devices is determined by the glass transition

temperature of the plastic, approximately 125°C. Temporarily

exceeding this limit may cause a shift in parametric performance

due to a change in the stresses exerted on the die by the package.

Exceeding a junction temperature of 125°C for an extended

period can result in device failure.

While the AD8114/AD8115 are internally short-circuit protected,

this may not be sufficient to guarantee that the maximum junction

temperature (125°C) is not exceeded under all conditions. To

ensure proper operation, it is necessary to observe the maximum

power derating curves shown in Figure 5.
