DAP

(2)

DAP N/A Connect to Ground

(2) There is an internal electrical connection between the exposed Die Attach Pad (DAP) and the GND pin of the device. Although the DAP

can be left floating, for best performance the DAP should be connected to the same potential as the device's GND pin. Do not use the

DAP as the primary ground for the device. The device GND pin must always be connected to ground.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
