I would want to know if the ADA4898 have enough bandwidth to amplify (simple non inverter stage) with a gain of 40 for large signal (+/-4V) with +/-6V power supply rails. The bandwidth required for my application is 350kHz, Could you please confirm that the gain bandwidth product is suffiscient ? How can I quantify the gain-bandwidth product since it seem to be dependant of the larger of the signal... ? Does it exist a relationship ?
I hope that you could help me.
