Power Requirements
3.3.4Power Requirements
The TPA301 audio evaluation module can operate from any voltage between approximately 2.5 V and 5.5 V, however, the TPA301 amplifier IC on the module is characterized for operation at 3.3 V and 5 V. For best performance (highest output power with lowest distortion), the module should be operated at approximately 5 V unless there is a specific reason for operating it from a lower voltage.
The TI
The platform is equipped with overvoltage and
VDD voltage applied to platform screw terminals J6 MUST NOT exceed the absolute maximum rating for the TPA301 amplifier IC installed on the evaluation module (6 V) or damage to the IC may result. In no case should VDD voltage of the incorrect polarity or in excess of 6.1 V be applied to screw terminals J6 of the platform, or the power protection circuit on the
-VDD line will trip.
VCC voltage applied to the platform MUST NOT exceed the maximum voltage input specified for the voltage regulator module installed in socket
U6 (12 V for the SLVP097), or damage to the voltage regulator module
may result. In no case should VCC voltage applied to the platform exceed 15 V, or the overvoltage protection circuit on the VCC bus will trip.
