What are the key Advantages of Instrumentation amplifiers? 3. It has very low DC offset. 2. This type of amplifier is in the differential amplifier family because it amplifies the difference between two inputs. Instrumentation Amplifiers are also used in hand held batteries. Voltage Gain is high as the configuration uses high precision resistors. The current I through the resistors R1, Rgain and R1 remains the same as ideally the current to the input stage Op-amps is zero. Instrumentation amplifier is very stable and hence ideal for long term use. Lost your password? The advantages of Instrumentation Amplifier are: 1. An instrumentation amplifier is an integrated circuit (IC) that is used to amplify a signal. It contains a higher amount of input impedance. They are used extensively in Bio-medical applications like ECG’s and EEG’s. The offset drift is attributable to temperature-dependent voltage outputs. 3. Compare this to the differential amplifier, … In addition, low noise is a common and desirable feature of instrumentation amplifiers. Applying Ohm’s law between the nodes E and F. Since there is no current flow to the input of the op-amps 1 & 2, the current I between the nodes G and H can be given as, The output of the difference amplifier is given by: –. The main advantages of using Instrumentation amplifiers are It has very low DC offset. Instrumentation amplifiers have single-ended output that floats on an externally-provided reference … Instrumentation amplifiers are precision devices having a high input impedance, a low output impedance, a high common-mode rejection ratio, a low level of self-generated noise and a low offset drift. This post will provide you a better understanding about what is Instrumentation Amplifier, its Working Principle, Applications, Advantages and Disadvantages. That is, the differential signal will be increased by gain and thus CMRR is directly proportional to gain. Advantages:Even a small value of input voltage can be amplified using instrumentation amplifier.Disadvantages:For transmission purpose for long range, noise also gets superimposed along … Advantages: . Advantages:Even a small value of input voltage can be amplified using instrumentation amplifier.Disadvantages:For transmission purpose for long range, … These and other advantages of the present invention will become more clear upon reading the following detailed description of the present invention in conjunction with the accompanying figures of which: FIG. The instrumentation amplifier is having advantages of high CMRR (ability to amplify the differential signal and suppress common mode signal), high … A high gain accuracy can be achieved by using precision metal film resistors for all the … Figure 2.85 shows the schematic representation of a precision instrumentation amplifier.
