Maximum Power Dissipation

The maximum safe power dissipation for the ADA4862-3 is

the die. At approximately 150°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

junction temperature of 150°C for an extended period can

result in changes in silicon devices, potentially causing

degradation or loss of functionality.

to the amplifier’s drive at the output. The quiescent power is the

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.
