Absolute maximum ratings Symbol Parameter Min Typ VCC Power supply voltage (pins VCCx) VDD Digital supply voltage (pins VDD_DIG) VDD PLL supply voltage (pin VDD_PLL) Top Operating junction temperature Tstg Storage temperature -0.3 - -0.3 - -0.3 - -20 - -40 - Max 24 4.0 4.0 150 150 Unit V V V °C °C Warning: Stresses beyond those listed in Table 3 above may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “Recommended operating conditions” are not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. In the real application, power supplies with nominal values rated within the recommended operating conditions, may experience some rising beyond the maximum operating conditions for a short time when no or very low current is sinked (amplifier in mute state). In this case the reliability of the device is guaranteed, provided that the absolute maximum ratings are not exceeded. 3.2 Thermal data Table 4.
