NOTE
The performance of the TPA3255EVM/TPA3255DDV is dependent on the power supply. Design the power supply with margins that can deliver the needed power. In low-frequency applications additional bulk capacitance may be needed. Replacing the bulk capacitors on the TPA3255EVM with more capacitance may be necessary, depending on the power supply used.
