General purpose op-amps are extremely versatile electronic devices that can be used to achieve a variety of different functions. A specialized op-amp circuit application is described as a controlled or constant energy source. This type of circuit has its output voltage or current determined by the magnitude of another independent voltage or current source. Operational amplifiers are often used as comparators that identify or compare the value of one input voltage to that of another input voltage. Specialized amplifier circuits make use of both open-and closed-loop configurations. Troubleshooting specialized amplifier circuits generally makes a comparison between the expected and actual output when a known input signal is applied. The closed-loop operation of specialized op-amp circuits are generally determined by the external components, including feedback resistors and capacitors that are connected to it. If the circuit is functioning properly, the output of the integrator should be a triangular waveform, which can be observed on an oscilloscope.
