The LT1364/1365 dual/quad, 70MHz GBW and 1000V/uS slew rate:
The simplified internal schematic is quite different than most traditional three-gain-stage V -> I -> V amps, looks like a cascade of "diamond"-configuration differential current amplifiers.
It's naturally not cheap about 6 bux in quantity for the quad, 12 in singles, but 1000V/uS and "stable into any capacitive load" wowie. anyone used them for anything here? The LTSpice test rig for the part is a 2MHz cutoff 4 pole Butterworth active filter from +5/-5 supplies.
