Case Temperature*

: The temperature measurement was taken at the hottest point on the MAQ5283 case mounted on a 2.25-square-inch PCB at an

ambient temperature of 25°C; see the “Thermal Measurements” section. Actual results depend on the size of the PCB, ambient temperature, and

proximity to other heat emitting components.
