Hi,
Please review your requirements:
* 0..2V range
* "precision requirements are not given"
* 24 bit resolution
--> 24bit at 2V range make a stepsize of 0.000000119 V/LSB.
It makes no sense, because other erros in your circuit will be at least a factor of 100 higher. (noise, thermal drift, aging, resistor tolerance... )
selection guide:
* go to a DAC manufacturer´s internet site and use the interactive DAC selection guide
* go to a distributor´s internet site and use the interactive DAC selection guide
