TAS5756M: Question about GVDD_REG power supply

Guru 14070 points

Part Number: TAS5756M

GVDD_REG power supply specification is not described in datasheet.

Waveform for startup sequence is attached below;

・On startup to 10 sec: 5.4V output and the after is 6.8V output.

・After I2C communication(Reset), GVDD is dropped to 5.4V for 1 sec and after become 6.8V.

Please let me know about two points question below;

①Is above waveform correct operation?

②Please let me know timing for read Vspk_GAIN/FREQ's  DC voltage.

Best regards,

Satoshi
