This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operations of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

The TPA3110D2 incorporates an exposed thermal pad on the underside of the chip. This acts as a heatsink, and it must be connected

to a thermally dissipating plane for proper power dissipation. Failure to do so may result in the device going into thermal protection

shutdown. See TI Technical Briefs SLMA002 for more information about using the TSSOP thermal pad.
