Maximum Power Dissipation

The maximum safe power dissipation in the ADA4430-1

package is limited by the associated rise in junction temperature

transition temperature, the plastic changes its properties. Even

temporarily exceeding this temperature limit can change the

stresses that the package exerts on the die, permanently shifting

the parametric performance of the ADA4430-1. Exceeding a

junction temperature of 150°C for an extended period can

result in changes in the silicon devices potentially causing

failure.

quiescent power dissipation and the power dissipated in the

package due to the load drive. The quiescent power is the

upon the particular application. The power due to load drive is

calculated by multiplying the load current by the associated

voltage drop across the device. RMS voltages and currents must

be used in these calculations.

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.
