Those two differential input pins are inverting pin or Negative and Non-inverting pin or Positive. An op-amp amplifies the difference in voltage between this two input pins and provides the amplified output across its Vout or output pin Op amp output impedance is an important factor in the design of any circuit. It determines the level of output voltage reduction when a load is applied. The output impedance or resistance is also important because any voltage dropped within the op amp itself will dissipate power and this may cause the op-amp temperature to rise significantly ** The first op amp to slew in this circuit is the 411, even though it is about 30 times faster than the 741 used in stage 1**. The reason for this is that it must handle signals 32 times as large. Note that if the final stage had a larger gain, say 5, the 318 would become the limiting factor

It's a differential amplifier in which two input terminals, a positive terminal and a negative terminal, are applied at the same point to create a single output In order for an op amp to receive the voltage signal as its input, the voltage signal must be dropped across the op amp. If you know the concept of a voltage divider, voltage drops primarily across components with high impedances, proportionally according to ohm's law by the formula V=IR
