However, the output impedance typically has a small value, which determines the amount of current it can drive, and how well it can operate as a voltage buffer.

An ideal op amp would have an infinite bandwidth BW , and would be able to maintain a high gain regardless of signal frequency. Op amps with a higher BW have improved performance because they maintain higher gains at higher frequencies; however, this higher gain results in larger power consumption or increased cost.

GBP is a constant value across the curve, and can be calculated with Equation 1 :. These are the major parameters to consider when selecting an operational amplifier in your design, but there are many other considerations that may influence your design, depending on the application and performance needs. Other common parameters include input offset voltage, noise, quiescent current, and supply voltages. In an operational amplifier, negative feedback is implemented by feeding a portion of the output signal through an external feedback resistor and back to the inverting input see Figure 3.

Negative feedback is used to stabilize the gain. This is because the internal op amp components may vary substantially due to process shifts, temperature changes, voltage changes, and other factors. The closed-loop gain can be calculated with Equation 2 :. There are many advantages to using an operational amplifier. Op amps have a broad range of usages, and as such are a key building block in many analog applications — including filter designs, voltage buffers, comparator circuits, and many others.

In addition, most companies provide simulation support, such as PSPICE models, for designers to validate their operational amplifier designs before building real designs. The limitations to using operational amplifiers include the fact they are analog circuits, and require a designer that understands analog fundamentals such as loading, frequency response, and stability. It is not uncommon to design a seemingly simple op amp circuit, only to turn it on and find that it is oscillating.

Due to some of the key parameters discussed earlier, the designer must understand how those parameters play into their design, which typically means the designer must have a moderate to high level of analog design experience. There are several different op amp circuits, each differing in function. The most common topologies are described below. The most basic operational amplifier circuit is a voltage follower see Figure 4. This circuit does not generally require external components, and provides high input impedance and low output impedance, which makes it a useful buffer.

Because the voltage input and output are equal, changes to the input produce equivalent changes to the output voltage. The most common op amp used in electronic devices are voltage amplifiers, which increase the output voltage magnitude. Inverting and non-inverting configurations are the two most common amplifier configurations. Both of these topologies are closed-loop meaning that there is feedback from the output back to the input terminals , and thus voltage gain is set by a ratio of the two resistors.

In inverting operational amplifiers, the op amp forces the negative terminal to equal the positive terminal, which is commonly ground. In this configuration, the same current flows through R2 to the output. The current flowing from the negative terminal through R2 creates an inverted voltage polarity with respect to V IN. This is why these op amps are labeled with an inverting configuration.

V OUT can be calculated with Equation 3 :. The operational amplifier forces the inverting - terminal voltage to equal the input voltage, which creates a current flow through the feedback resistors. The output voltage is always in phase with the input voltage, which is why this topology is known as non-inverting. Note that with a non-inverting amplifier, the voltage gain is always greater than 1, which is not always the case with the inverting configurations.

VOUT can be calculated with Equation 4 :. An operational amplifier voltage comparator compares voltage inputs, and drives the output to the supply rail of whichever input is higher. This configuration is considered open-loop operation because there is no feedback. Voltage comparators have the benefit of operating much faster than the closed-loop topologies discussed above see Figure 7.

The section below discusses certain considerations when selecting the proper operational amplifier for your application. Firstly, choose an op amp that can support your expected operating voltage range. A negative supply is useful if the output needs to support negative voltages. If your application needs to support higher frequencies, or requires a higher performance and reduced distortion, consider op amps with higher GBPs. One should also consider the power consumption, as certain applications may require low-power operation.

Power consumption can also be estimated from the product of the supply current and supply voltage. Generally, op amps with lower supply currents have lower GBP, and correspond with lower circuit performance. Operational amplifiers are widely used in many analog and power applications. The benefits of using an op amp are that they are generally widely understood, well-documented and supported, and are fairly easy to use and implement.

Op amps are useful for many applications, such as voltage buffers, creating analog filters, and threshold detectors. With a greater understanding of key parameters and common topologies related to operational amplifiers, you can begin implementing them in your circuits.
