Best slew rate/settling time currently achievable

Many precision DAC's like AD5504 and AD5535B are tuned for high DC performance, not for settling time. The precision high voltage DAC slew rates are less than 10V/us, with settling times typically about 60us.  The high-speed current drive amp, ADA4870, supports 2500V/us typ with 82ns typ settling time.
