LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
THERMAL CHARACTERISTICS
Note
1. Thermal resistance from junction to ambient is determined with the IC soldered on a standard single sided
57x57x1.6mm FR4 epoxy PCB with 35
m thick copper traces. The measurements are performed in free air.
