Web25 de abr. de 2024 · Technically an op amp that normally is powered by dual supply can be used in single supply if input and output signals are small enough and don’t go to rail voltages. That is if you power off 12V and set input and output at 6V where input is 1Vpp and output is 2Vpp then your fine since you’ve got plenty of headroom. WebAn alternate circuit, Figure 3b, does not limit the output with low load impedance. It provides a small amount of positive feedback to reduce the net feedback factor.
