Figure 7. Exposed Paddle
Note that the exposed paddle on this package is an electrical connection as well as a thermal enhancement. For the device to
function properly, the paddle must be soldered to a PCB land that functions as both a heat dissipation path as well as an electrical
ground (analog).
