DAC5662: Power sequence

Hoang Duong

Part Number: DAC5662

Tool/software:

Hi Ti team,

Is there any required for power on/off sequence for DAC5662?

In the datasheet it is noted that Voltage between AVDD and DVDD is +-0.5V. During power on/off, can I power up AVDD before DVDD?

Also is there a contact I can email for schematic review regarding DAC5662?

Thanks.

Hi Hoang,

The AVDD and DVDD need to be within 500mV during power up/down. This means that either can power up first but the other cannot be less than 500mV below the other.

Regards,

Geoff
