Hi Team,

May I know what is the AVDD,AVCC,DVDD power on reset threshold? I only find 4.5V in section 8.3 and 3.9V in section 6.7. Thanks. The application is apply AVCC/AVDD/DVDD=5V.

Hi Lucas,

The reset values are going to be closer to what you see in section 6.7. The AVDD and DVDD power supplies likely reset around 3.9V.

AVCC only powers the DAC buffers, so this supply being low does not reset the device.

Thanks,
Erin
