• OpAmp is a high gain open-loop stage, which acts like an ideal operational amplifier; for normal operation, gain control is necessary via feedback components.
• This block can be used as an ideal operational amplifier to produce summing stages, active filters, gain stages, and integrators.
• OpAmp is not the same device created by the OpAmp macromodel product. The OpAmp macromodel product can create a new device each time you use it. The symbol and the accompanying models for the OpAmp macromodel are different from those used within this opAmp component.
