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 may affect device reliability.

The θJA values in Table 6 assume a 4-layer JEDEC standard

board. If the thermal pad is soldered to the board, then it is

also assumed it is connected to a plane. θJC at the exposed pad

is 4.4°C/W.

Maximum Power Dissipation

The maximum safe power dissipation for the AD8222 is limited

by the associated rise in junction temperature (TJ) on the die. At

approximately 130°C, which is the glass transition temperature,

the plastic changes its properties. Even temporarily exceeding

this temperature limit may change the stresses that the package

exerts on the die, permanently shifting the parametric performance

of the amplifiers. Exceeding a temperature of 130°C for an

extended period can result in a loss of functionality.

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.
