In the previous chapter, the basic properties of operational amplifiers were summarized, and a number of standard configurations were discussed. It was shown, for example, that very simple arrangements of a few resistors in combination with an op-amp could provide noninverting or inverting amplification. These circuits are actually both usable and useful for boosting weak sensor signals and for performing analog addition and subtraction.
