Digital to Analog conversion in Multisim
Since your ADC is only 8 bits, and the DACs you show are 16 bits, I'd say neither - look for an 8 bit DAC (although you could use the 16 bit parts, and tie the lowest 8 bits to ground).

Read the datasheets for those parts (or any other you might find) to find the features of each, and how to use them.
