Note:

2. Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;

functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability

may be affected by exposure to absolute maximum rating conditions for extended periods of time.

3. U-QFN3030-16 dissipation is based on a two-layer 2oz. copper 2”x 2” FR4 substrate PCB with thermal vias to the bottom layer.
