Hello Audio Folks, can anyone help on below two questions from customer.
1. In system power on, customer GVDD and VDD will have an over shoot up to 13.2V. In the worst case, it can even reach 14.8V. The over shoot is around 2ms. After 2ms, then, it will fall back to 12.5V. In data sheet, both recommended and abs max only allow 13.2V. Will it be a problem? Below is the waveform.
2. For GVDD and VDD current, the total current is only 20mA + 12mA = 32mA in data sheet. But customer finds that the actual current is much much higher than this in power on. They want to know the exact value.
Regards,
Kes
