Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only and 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

Junction Temperature

The maximum power that can be safely dissipated by the

ADSY8401 is limited by its junction temperature. The

maximum safe junction temperature for plastic encapsulated

devices as determined by the glass transition temperature of the

plastic is approximately 150°C. Exceeding this limit temporarily

might cause a shift in the parametric performance due to a

change in the stresses exerted on the die by the package.

Exceeding a junction temperature of 150°C for an extended

period can result in device failure.

Exposed Paddle

The die paddle must be in good thermal contact with at least a

partial plane for proper operation in high ambient temperature

environments. The partial plane must be in good electrical

contact with AVCC or AGND for reliable electrical operation.

See the PCB Design for Optimized Thermal Performance

section for more information on the use of the exposed paddles

to dissipate excess heat.

ESD 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 this product 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.
