OpAmp-Slide24

Shown here again is the AD711 amplifier with the same gain of 2, but with the frequency reduced to 2MHz. Looking at the gain bandwidth product and the slew rate, this amplifier can confidently create the output signal needed. However, a yellow error flag is thrown here as the gain error exceeds 1% because the closed loop gain is operating so close to the open loop gain at this frequency.
