WebOnce feedback is applied to the op amp, it is possible for the op-amp circuit to become unstable. Certain amplifiers belong to a family called internally compensated op amps; … Web30 de jan. de 2015 · Actually, an op amp gain of 1 (100% feedback) is the worst-case for op amp stability. If it's stable at a gain of 1 it will be more stable at higher gains (less feedback). Some high frequency op amps are not even compensated for a gain of 1, only for gains greater than 1 (such as ≧5). R9 (or R11) has no effect on the stability.
