Configuration

2.1 Configuration

The platform switch and jumper settings shown in Table 2–1 are typical for the TPA3001D1EVM and cause the TPA3001D1 to shut down when a plug is inserted into platform headphone jack J10 (see Note 3 in Table 2–1).

2.2 Precautions

Power Supply Input Polarity and Maximum Voltage

Always ensure the polarity and voltage of the external power connected to VCC power input connector J1, J2, and/or VDD power input connector J6 are correct. Overvoltage or reverse-polarity power applied to these terminals can open onboard soldered-in fuses and cause other damage to the platform, installed evaluation modules, and/or the power source.

Inserting or Removing EVM Boards

Do not insert or remove EVM boards with power applied. Damage to the

EVM board, the platform, or both may result.
