So op amps are much more versatile than instrumentation amplifiers. INAs are precision amplifiers with a closed-loop gain over a set range.

Precision amplifiers are op amps that have better specifications and are more accurate than your average op amp. Precision op amps have precisely matching resistors etched in the substrate at the chip level. Precision op amps are necessarily integrated chips so that the components are precisely matched. INAs do not have an external feedback. Op amps have external feedback loops that can be set by the user. In this way, INAs are often used for their ability amplify differential gain, so only the signal that is not the same in both inputs is what is amplified and presented as output by the INA.

Nevertheless, you can build an INA with opamps and resistors, and INAs and op amps will have similar specifications in their respective datasheets.

INAs share specs like offset voltage, offset voltage drift, and input bias current. INAs are not op amps, but precision amplifiers that provide gain and have great difference-amplification and CMR properties.

A precision amplifier, on the other hand, could be an op amp with excellent characteristics good specs. A precision device of any type has better specs with lower margins of error. A single silicon wafer will yield a small number of devices that test as more precise or more accurate.

As such, it is reasonable to expect that precision-rated ICs will demand a premium in price.

The AD620 Datasheet: A Low Cost, High Accuracy Instrumentation Amplifier

The AD is a low cost, low power, extremely low noise, ultra-low bias current, high speed instrumentation amplifier which is ideally suited for a broad spectrum of signal conditioning and data acquisition applications. This breakthrough product features the highest CMRR available, allowing it to extract low-level signals in the presence of high-frequency common mode noise over a wide temperature range. The AD has excellent distortion performance, allowing use in demanding applications such as vibration analysis. For applications with significant source impedance, the AD employs novel process technology and innovative design techniques to provide groundbreaking noise performance limited only by the sensor.

With a low distortion of dB, the AD is robust enough for applications that demand reduced size, power and distortion levels, such as healthcare instrumentation, precision data acquisition equipment and industrial vibration analysis. The CMRR increases with the gain to provide high signal rejection when it is needed most, and ADI's high-performance pin configuration allows the AD to reliably maintain high CMRR at frequencies well beyond those of typical instrumentation amplifiers. Gain is set from 1 to 10, with a single resistor, and a reference pin allows the user to offset the output voltage. The feature can be useful to shift the output level when interfacing to a single-supply signal chain. More information about the AD instrumentation amplifier at www.

INA128P Precision Low-Power Instrumentation Amplifier

In this tutorial, we will learn about few important Instrumentation Amplifier Basics and Applications and also the circuit and working of a three Op-amp Instrumentation Amplifier. Many industrial and consumer applications require the measurement and control of physical conditions. For example, measurements of temperature and humidity inside a diary plant to accurately maintain product quality, or precise control of the temperature of a plastic furnace to produce a particular grade of plastic, etc. These changes in physical conditions must be converted to electrical quantities using transducers, and then amplified.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I'm making a low power weighing scale with good precision. I understand the laser trimmed resistances in the INA would make the gain precise. A proper instrumentation amplifier require the use of very closely matched resistors. Laser trim is a practical way to trim ICs fabricated on a bipolar wafer process. It is used widely not only for op amps, but also in difference and instrumentation amplifiers to improve the resistor matching that is critical in minimizing gain error while optimizing common-mode rejection ratio CMRR performance.
