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.

(1) Maximum power dissipation may be limited by overcurrent protection

(2) Power rating at a specific ambient temperature T_Ashould be determined with a junction temperature of 150°C. This is the point where

distortion starts to substantially increase. Thermal management of the PCB should strive to keep the junction temperature at or below

150°C for best performance and long-term reliability. See power dissipation estimate in application section of this data sheet for more

information.

(3) Test boards conditions:

(a) 2 inches x 2 inches, 4 layers, thickness: 0.062 inch

(b) 2 oz. copper traces located on the top of the PCB

(d) 4 thermal vias (10mil) located under the device package
