Applications that require dc coupling can also benefit by driving the AD9241 differentially. Since the signal swing requirements of each input is reduced by a factor of two in the differential mode, the AD9241 can be configured for a 5 V input span in a +5 V or ±5 V system. This allows various high performance op amps specified for +5 V and ±5 V operation to be configured in various differential driver topologies. The optimum op amp driver topology depends on whether the common-mode voltage of the single-ended-input signal requires level-shifting.
