In the preceding paragraphs we have discussed the effects of op-amp limitations, taking the example of the simple inverting voltage amplifier circuit. Thus, for example, op-amp input current caused a voltage error at the output. In a different op-amp application you may get a different effect; for example, in an op-amp integrator circuit, finite input current produces an output ramp (rather than a constant) with zero applied input. As you become familiar with op-amp circuits you will be able to predict the effects of op-amp limitations in a given circuit and therefore choose which op-amp to use in a given application. In general, there is no "best" op-amp (even when price is no object): For example, op-amps with the very lowest input currents (MOSFET types) generally have larger voltage offsets and greater noise, and vice versa. Good circuit designers choose their components with the right trade-offs to optimize performance, without going overboard on unnecessary "gold-plated" parts.
