The TAS5121I package is thermally enhanced for conductive cooling using an exposed metal pad area. It is impractical to use the
devices with the pad exposed to ambient air as the only heat sinking of the device.
Therefore RθJA, a system parameter that characterizes the thermal treatment, is provided in the Thermal Information section. This
information should be used as a reference to calculate the heat dissipation ratings for a specific application.
