(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is specified and do not imply guaranteed performance limits. For specified performance limits and
associated test conditions, see the Electrical Characteristics table. All voltages are with respect to the potential at the GND pin, unless
otherwise specified.
(2) Refer to TI’s packaging website for more detailed information and mounting techniques.
