? Stresses beyond those listed under “ absolute maximum ratings ” may cause permanent damage to the device. These are stress ratings only, and
functional operation 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.
? Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals. Consult
Packaging Information section of the Portable Products Databook (TI Literature No. SLUD001) for thermal limitations and considerations of
packages. All voltages are referenced to the AN4 terminal.
