Hi,
If AVCC and PVCC voltage is less than a clipping level of PLIMIT setting, the Tina-TI transient simulation of TPA3130D2 outputs a mysterious wave pattern as shown below when input signal level is over the clipping level.
figure 1. AVCC and PVCC is 9.0V.
figure 2. AVCC and PVCC is 8.9V.
figure 3. AVCC and PVCC is 8.8V.
figure 4. AVCC and PVCC is 8.7V.
figure 5. AVCC and PVCC is 8.6V.
figure 6. simulation circuit
Because I don't have a TPA3130D2EVM, please tell me whether real TPA3130D2 device outputs such as the above mysterious wave pattern.
Best regards,
Akio Ito
