The dependence of the MUSES8920 PD on ambient temperature is shown in Fig 1. The plots are depended on following two points. The first is PD on ambient temperature 25C, which is the maximum power dissipation. The second is 0W, which means that the IC cannot radiate any more. Conforming the maximum junction temperature Tjmax to the storage temperature Tstg derives this point. Fig.1 is drawn by connecting those points and conforming the PD lower than 25C to it on 25C. The PD is shown following formula as a function of the ambient temperature between those points. Dissipation Power PD = Tjmax - Ta ja [W] (Ta=25C to Ta=150C) Where, ja is heat thermal resistance which depends on parameters such as package material, frame material and so on. Therefore, PD is different in each package. While, the actual measurement of dissipation power on MUSES8920 is obtained using following equation. (Actual Dissipation Power) = (Supply Current Icc) X (Supply Voltage V+- V-) - (Output Power Po) The MUSES8920 should be operated in lower than PD of the actual dissipation power. To sustain the steady state operation, take account of the Dissipation Power and thermal design.
