Hi Sirs,

Would you please advise the TAS2557's VDDIO power consumption data as well as VBAT, AVDD and DVDD rails in each power status for customers' power budget evaluation?

Thank you and Best regards,

Hi Wayne,

I don't have this data in each state of the device, but the maximum current of the digital I/O supply is 5 mA according to the datasheet.
Please let me know if you need further information.

Best Regards

Hello Jose,

5mA is in active mode. Please advise the official 3.3V VDDIO power consumption data in shutdown modes because customer is going to make decision to shutdown the VDDIO or not in standby mode.

Thank you and Best regards,

Hi Wayne,

I have gotten the data. Below you can watch the results.

Power consumption with digital input and speaker protection disabled	IOVdd=14uA
Power consumption with digital input and speaker protection enabled	IOVdd=40uA
Power consumption in hardware shutdown	IOVdd=0.1uA
Power consumption in software shutdown	IOVdd=0.1uA
