(1) 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.
(2) If the AIC28 is used to drive high power levels to an 8- load for extended intervals at an ambient temperature above 80°C, multiple vias should
be used to electrically and thermally connect the thermal pad on the QFN package to an internal heat dissipating ground plane on the user’s PCB.
