Non-Ideal Properties a) Output limit – bounded by V pos and V neg b) Slew-rate limitation; c) Bandwidth limitation SLEW-RATE LIMITATION Ideal op-amp Real op-amp Output changes instantaneously Rate of change slew rate Limitation due to internal circuitry (capacitances) v IN t 1 -1 v OUT t 12 -12 v IN v OUT + - 12 -12 Op-amp driven to slew-rate limits nonlinear output behavior
