About the thermal design by the IC
Characteristics of an IC have a great deal to do with the temperature at which it is used, and exceeding absolute
maximum ratings may degrade and destroy elements. Careful consideration must be given to the heat of the IC from the
two standpoints of immediate damage and long-term reliability of operation.
Power dissipation values vary according to the board on which the IC is mounted.
