Note: The MAX9770 thin QFN package features an exposed thermal pad on its underside. This pad lowers the package’s thermal resis-
tance by providing a direct heat conduction path. Due to the high efficiency of the MAX9770’s Class D amplifier, additional
heatsinking is not required. The voltage of the exposed paddle is -V
DD and it is important that the exposed paddle is NOT con-
nected to the ground plane. It should be either left floating or can be tied to the CPV SS pin. See the MAX9770 EV kit data sheet for
suggested component values and layout guidelines.
