DAC with 10-bit i2c addressing support?

Hi,

 

I'm looking for a 10-bit DAC that can support 8+ devices on a single bus. The analog outputs must be isolated from each other, so a multi-channel device won't work.

 

The end goal is to have 8+ analog outputs on the same bus. I would prefer to use i2c, but SPI is also an option. With i2c, most devices only have 1 or 2 address select pins, supporting up to 4 devices. Is there a DAC that can support more addresses than this using i2c's 10-bit addressing scheme? Or a better way to do this?

 

Thanks for the advice.
