Hi LTZ2000,
This....
But what would be the "industry standard fast op-amp"? Low cost, available almost everywhere.Is looking for the holy grail...
Faster opamp you can buy, are all relatively bad DC performers.
You can use somthinge like the old LM318 and use some feedforeward, but, not so good DC performance.
Why not use a AD736 or a LTC1968, but be shure to use the right level (dynamic range)
To make your schematic better, use low power schottky diode's for a lower voltage drop and more speed.
Keep the resistance value is relatively low, use bias compensation resistors on the + inputs of the opamp.
The are there are plenty of fast opamps available from Analog, Linear and TI, but no yelly beans...
Kind regarts,
