(1) For the most current product and ordering information, see the Package Option Addendum located at the end of this data sheet.

(2) Thermal pad size: 6.17 mm x 6.17 mm (min), 7,5 mm x 7,5 mm (max). θja = 21°C/W (no airflow) or 15°C/W (with 200 LPFM airflow),

θjc = 13.5°C/W, and θjp (to the bottom PowerPad) = 2°C/W when used with 2 oz. copper trace and pad soldered directly to a JEDEC standard

four layer 3 in x 3 in PCB.

(1) Stresses above these ratings may cause permanent damage.

Exposure to absolute maximum conditions for extended periods

may degrade device reliability. These are stress ratings only, and

functional operation of the device at these or any other conditions

beyond those specified is not implied.

(2) For more details, see the Input Voltage Overstress section in this

data sheet.

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.
