Probably no single issue faces more high-speed signal path designers (and supplier support teams) than the risk of instability in higher speed op amps and fully differential amplifiers (FDA).
DC Precision Considerations for High Speed Current Feedback and Fully Differential Amplifiers, Insight #4

The more recent Fully Differential Amplifiers (FDA) offer both CFA and VFA versionsThe CFA based versions will also have poor DC accuracy while more recent “precision” VFA based FDAs can provide much improved DC accuracy. Those VFA-based FDAs do come with some added DC error sources beyond the typical op amp terms that will be described here
