If the voltage output is buffered, it will indicate this on the datasheet and the output impedance will be low. An indicator in the datasheet that the DAC is unbuffered is that the parameters will be specified unloaded. If it is unbuffered, it will typically be high impedance and will need to be buffered due to the fact that any loading on the output will lead to error in the output voltage.
