Hello,

Our customer use the TLV320AIC3104.

The datasheet has a power supply recommendation about power up.

How about power down sequence?

The customer power down the AVDD before the DVDD. Is it OK?

Best Regards,

Hello, Aoyama-san,

We don't have a specific power down sequence for this device. However, we recommend to separate analog from digital activity in codecs. So, I would suggest to power down the the analog supplies and digital supplies at different time as customer is doing.

Best regards,
