Notes:
1. Stresses greater than 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 Ratings” for extended periods may affect device reliability.
2. Chip is soldered to 200mm2 copper (top side solder mask) of 1oz. on PCB with 8x0.5mm vias.
