In order to obtain the best system level ESD performance, a standard pull-up resistor (10 k typical) is
required for any address pin connecting to V
performance, please refer to application notes AN10897 and AN11131.
HTSSOP28 package supply ground is connected to both V
be connected to supply ground for proper device operation. For enhanced thermal, electrical, and board
level performance, the exposed pad needs to be soldered to the board using a corresponding thermal pad
on the board and for proper heat conduction through the board, thermal vias need to be incorporated in the
PCB in the thermal pad region.
