Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

soldered in a circuit board for surface-mount packages. This
was measured using a standard 4-layer board. For the LFCSP
package, solder the exposed pad to a copper plane, which
should be connected to V+.
