NOTE: The performance of the TPA3251EVM/TPA3251D2DDV is dependent on the power supply.
Design the power supply with margins that can deliver the required power. Some low-
frequency applications can require additional bulk capacitance. Replacing the bulk capacitors
on the TPA3251EVM with 3300 µF or more capacitance can be necessary depending on the
power supply used.
2.4.1 Performance Data (SE Mode)
All measurements are taken at audio frequency = 1 kHz, PVDD_X = 36 V, RL = 4 Ω, fS = 600 kHz, ROC
= 22 kΩ, Output filter: L = 7 μH, C = 0.68 µF, with AES17 + AUX-0025 measurement filters.
