A general‐purpose nonlinear macromodel of an operational amplifier is presented. All element values can be derived directly from typical specification sheets eliminating any testing to determine model parameters. The model simulates the following characteristics: voltage and current offsets, input impedance, nonlinear input bias currents, gain, multiple poles, nonlinear slew, common‐mode gain, voltage and current limiting and output impedance.
