Notes:

1. Includes margin limits.

2. ΘJA is measured in free air with the device mounted on a multi-layer FR4 test board and the exposed metal pad soldered to a low impedance

ground plane using multiple vias.

3. For ΘJC, the “case” temperature is measured at the center of the exposed metal pad.
