We use ADA4896 as unity gain buffer, single power supply (0V, +5V). Schematics is attached to the message. We connect input to the laboratory voltage source. We observe oscillations at ~90MHz. The amplitude of the oscillations varies between 0.3V and 3V depending on input voltage changes. We checked also input voltage-it is clean. Datasheet and openloop gain/phase plots say ADA4896 is unity gain stable with large phase margin. Please advise!
