What are operational amplifiers for?
Op-amps can be used for many purposes, including amplifying audio signals, filtering out unwanted frequency components and performing mathematical calculations. In addition, they can be used to convert DC voltage levels into more useful AC waveforms or to condition signals before they enter an analog-to-digital converter (ADC). Op-amps are also essential components in some control systems, such as those used in motor controllers and robotic arms.
Op-amps are typically powered by dual power sources, one positive and one negative. The positive source is connected to the op-amp’s output while the negative source is connected to the op-amp’s inverting input. This allows the signal at the noninverting input to be amplified and produces an output voltage that is proportional to the input.
Op-amps can also be used in combination with other components such as resistors, capacitors and transistors to create more complex circuits. Op-amp circuits can be used for signal processing, too, such as integrating and differentiating signals or creating oscillators and filters. These circuits are often seen in audio equalizers and other sound-processing equipment. Op-amps are also used in many scientific and industrial applications, such as temperature and pressure sensors or instrumentation amplifiers used to measure very small signals.
By combining multiple op-amps, even more complex circuits can be created. This includes analog computers, which use op-amp circuits to perform mathematical operations like addition, subtraction and multiplication. Such computers can be used in automatic control systems or embedded in other electronic equipment. Op-amps are also essential components of analog synthesizers, which convert electrical signals into musical notes [1].
