Not all amplifiers used in instrumentation applications are instrumentation amplifiers, and by no means are all in-amps used only in instrumentation applications.
In-amps are used in many applications, from motor control to data acquisition to automotive. The intent of this guide is to explain the fundamentals of what an instrumentation amplifier is, how it operates, and how and where to use it.
In addition, several different categories of instrumentation amplifiers are addressed in this guide. When sensing a signal, the bridge resistor values change, unbalancing the bridge and causing a change in differential voltage across the bridge. In addition, a constant dc voltage is also present on both lines.
This dc voltage will normally be equal or common mode on both input lines, ic op amp cookbook pdf free download. In its primary function, ic op amp cookbook pdf free download, the in-amp will normally reject the common-mode dc voltage, or any other voltage common to both lines, while amplifying the differential signal voltage, the difference in voltage between the two lines. With the input signal applied across the two differential inputs, gain is either preset internally or is user set via pins by an internal or external gain resistor, which is also isolated from the signal inputs.
An instrumentation amplifier is a closed-loop gain block that has a differential input and an output that is single-ended with respect to a reference terminal. Most commonly, the impedances of the two input terminals are balanced and have high values, typically , or greater. The input bias currents should also be low, typically 1 nA to 50 nA. As with op amps, output impedance is very low, nominally only a few milliohms, at low frequencies. AD bridge circuit. In contrast, if a standard op amp amplifier circuit were used in this application, it would simply amplify both the signal voltage and any dc, noise, or other common-mode voltages.
As a result, the signal would remain buried under the dc offset and noise. Because of this, even the best op amps are far less effective in extracting weak signals. Figure contrasts the differences between op amp and in-amp input characteristics.
Signal Ic op amp cookbook pdf free download and Common-Mode Rejection An instrumentation amplifier is a device that amplifies the difference between two input signal ic op amp cookbook pdf free download while rejecting any signals that are common to both inputs. The in-amp, therefore, provides the very important function of extracting small signals from transducers and other signal sources. Common-mode rejection CMRthe property of canceling out any signals that are common the same potential on both inputswhile amplifying any signals that are differential a potential difference between the inputsis the most important function an instrumentation amplifier provides, ic op amp cookbook pdf free download.
Both dc and ac common-mode rejection are important in-amp specifications. Any errors due to dc common-mode voltage i. Fortunately, most modern monolithic IC in-amps provide excellent ac and dc common-mode rejection. It is the net gain or ic op amp cookbook pdf free download from input to output for voltages common to both inputs. The differential or normal mode gain AD is the gain between input and output for voltages applied differentially or across the two inputs. The commonmode rejection ratio CMRR is simply the ratio of the differential gain, AD, to the common-mode gain.
Note that in an ideal in-amp, ic op amp cookbook pdf free download, CMRR will increase in proportion to gain.
Common-mode rejection is usually specified for full range common-mode voltage CMV change at a given frequency and a specified imbalance of source impedance e. Mathematically, common-mode rejection can be represented as where: AD is the differential gain of the amplifier; VCM is the common-mode voltage present at the amplifier inputs; VOUT is the output voltage present when a common-mode input signal is applied to the amplifier.
The term CMR is a logarithmic expression of the common-mode rejection ratio CMRR. To be effective, an in-amp needs to be able ic op amp cookbook pdf free download amplify microvolt-level signals while rejecting common-mode voltage at its inputs. It is particularly important for the in-amp to be able to reject common-mode signals over the bandwidth of interest.
This requires that instrumentation amplifiers have very high common-mode rejection over the main frequency of interest and its harmonics. Op amp vs. in-amp input characteristics. At unity gain, typical dc values of CMR are 70 dB to more than dB, with CMR usually improving at higher gains.
While it is true that operational amplifiers connected as subtractors also provide common-mode rejection, the user must provide closely matched external resistors to provide adequate CMRR.
On the other hand, monolithic in-amps, with their pretrimmed resistor networks, are far easier to apply.
