Op-Amps or Operational Amplifiers are widely used integrated circuits in analog circuits due to their high gain, high input impedance, low output impedance, and excellent linearity.
They are commonly used in various applications such as amplifiers, comparators, oscillators, filters, and many more. The LM358 and LM741 are some of the most commonly used Op-Amp ICs, but there are many other types available on the market.
The versatility of Op-Amps lies in their ability to be configured in many different ways for different applications. They can be used as voltage amplifiers, current amplifiers, inverting amplifiers, non-inverting amplifiers, differentiators, integrators, and more. They can also be used as comparators to compare two different input signals and provide an output based on the comparison.
Circuit Digest offers a wide variety of Op-Amp circuits with circuit diagrams and hardware explanations that make it easy for beginners to understand the basics of operational amplifiers. Here are some examples of Op-Amp circuits that can be found on Circuit Digest:
Non-Inverting Amplifier Circuit
A non-inverting amplifier is an Op-Amp circuit that amplifies the input voltage and provides an output voltage that is in-phase with the input signal. This circuit is commonly used in audio amplifiers, signal conditioners, and other applications where a high-gain amplifier is required. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Inverting Amplifier Circuit
An inverting amplifier is an Op-Amp circuit that amplifies the input voltage and provides an output voltage that is 180 degrees out of phase with the input signal. This circuit is commonly used in audio amplifiers, signal conditioners, and other applications where a high-gain amplifier is required. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Voltage Follower Circuit
A voltage follower is an Op-Amp circuit that provides an output voltage that is equal to the input voltage. This circuit is commonly used in applications where the input impedance needs to be high, and the output impedance needs to be low. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Comparator Circuit
A comparator is an Op-Amp circuit that compares two input voltages and provides an output based on the comparison. This circuit is commonly used in applications such as level detection, threshold detection, and many more. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Integrator Circuit
An integrator is an Op-Amp circuit that performs the mathematical operation of integration. This circuit is commonly used in applications such as waveform generation, filter circuits, and many more. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Differentiator Circuit
A differentiator is an Op-Amp circuit that performs the mathematical operation of differentiation. This circuit is commonly used in applications such as waveform analysis, filter circuits, and many more. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Summing Amplifier Circuit
A summing amplifier is an Op-Amp circuit that adds two or more input voltages and provides an output voltage that is the sum of all the input voltages. This circuit is commonly used in audio mixers, signal conditioners, and many more. The circuit diagram and hardware explanation for this circuit can be found on Circuit Digest.
Schmitt Trigger Circuit
A Schmitt trigger is an Op-Amp circuit that provides hysteresis to a signal, which means that the output switches at different input voltage levels depending on whether the input is rising or falling. This circuit is commonly used in applications such as signal conditioning, noise filtering.
In conclusion, Op-Amps or Operational Amplifiers are an essential component in analog circuit design. They can be configured in many different ways to suit a variety of applications such as amplifiers, comparators, integrators, differentiators, summer, voltage follower, and more.
