Description
Description
Beyond the primitive transistor, the operational amplifier is the most basic building block for analog applications. Fundamental functions such as gain, load isolation, signal inversion, level shifting, adding and/or subtracting signals are easily implemented with this building block. More complex circuits can also be implemented, such as the instrumentation amplifier, a current to voltage converter, and filters, to name only a few. Regardless of the level of complexity of the operational amplifier circuit, knowing the fundamental operation and behavior of this building block will save a considerable amount of upfront design time.
