1. Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
2. T_J is calculated from the ambient temperature T_A and power dissipation P_D according to the following formula: T_J = T_A + P_D x θ_JA.
3. Thermal resistance is specified with approximately 1 square inch of 1 oz copper.
