Thermal Pad

(bottom side)

The

Thermal Pad

of the QFN package (bottom side) is to be connected to a ground plane on the PCB which

must have GND potential. GNDA must be wired to GND.

Only pin 1 marking on top or bottom defines the package orientation (iC-TW2 label and coding is subject

to change).
