I plan to operate the Sabre32 DAC in current output mode. So I need a I/V stage. The one design I've seen, uses a pair of TI's OPA1632, which are fully differential. On the other hand, ESS's Maximizing DAC Performance for Every Budget, says the best performing part they tested was Analog Device's AD797. I can use a pair of them, and still get a balanced, differential output.
