NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent 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.

2Specification is for device in free air (TA = 25°C):

80-lead plastic LQFP (ST): θJA = 48°C/W.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD8110/AD8111 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 150°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.

AD8110/AD8111

Exceeding a junction temperature of 175°C for an extended

period can result in device failure.

While the AD8110/AD8111 is internally short circuit protected,

this may not be sufficient to guarantee that the maximum junction

temperature (150°C) is not exceeded under all conditions. To

ensure proper operation, it is necessary to observe the maximum

power derating curves shown in Figure 3.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the AD8110/AD8111 features proprietary ESD protection circuitry, permanent damage may occur

on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions

are recommended to avoid performance degradation or loss of functionality.

WARNING!
