Letting Operational Amplifiers Do the Tough Math Fast

In This Chapter

arrow Performing hand calculations electronically with operational amplifiers

arrow Modeling secrets of operational amplifiers with dependent sources

arrow Taking a look at op-amp circuits

arrow Putting together some systems

The operational amplifier (op amp) is a powerful tool when you’re working with active devices in modern-day circuit applications. Because op amps can do calculations electronically, they perform mathematical operations (like addition, subtraction, multiplication, division, integration, and derivatives) fast. You can put together basic op-amp circuits to build accurate mathematical models that predict complex and real-world behavior — like when the breakfast pastry in your toaster will turn into a flaming torch.

This chapter introduces op-amp circuits, demonstrates how to use them to perform certain mathematical operations, and gives you a peek at the more complex processing actions that op amps serve as the building blocks for.
