DAC5672A: vs DAC5672, can the "A" version be used with 1.8V DVDD and 3.3V AVDD

Hello,

I saw this E2E post: https://e2e.ti.com/support/data-converters/f/73/t/726250, which mentions that the DAC5672A can be used with separate AVDD and DVDD supplies. Originally I took that as meaning the supplies can be a different voltage, looking over the datasheet, this doesn't seem to be the case as AVDD and DVDD are both 3-3.6V range.

If the DAC5672A can't be used with 1.8V DVDD and 3.3V AVDD. Do we have a device similar to the DAC5672A that can support this configuration?

1.8V DVDD and 1.8V AVDD is also acceptable.

Thanks,
Nick
