The instrumentation amplifier As suggested before, it is beneficial to be able to adjust the gain of the amplifier circuit without having to change more than one resistor value, as is necessary with the previous design of differential amplifier. The so-called instrumentation builds on the last version of differential amplifier to give us that capability: It is used primarily for testing instruments and to measure the calibration as well as output of various equipments. The circuit requires three op-amps all together; I have used two LM358 ICs. Instrumentation Amplifier Application Note (PDF 35p) Currently this section contains no detailed description for the page, will update this page soon. An instrumentation amplifier (InAmp) is an integrated circuit or operational amplifier topology that has high input impedance differential inputs and a low impedance single-sided output. In the past, the term instrumentation amplifier (INA) was often misused, referring to the application rather than the device’s architecture. ELECTRICAL!ENGINEERING!43/100!

The circuit architecture is designed for high bandwidth at high gain. The op-amp instrumentation amplifier circuit that I am using is given below. The instrumentation amplifier (IA) is one of the crucial blocks in an electrocardiogram recording system. 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. In the specification tables this value describes performance The offset drift is attributable to temperature-dependent voltage outputs. Conclusion Instrumentation Amplifiers An instrumentation (or instrumentational) amplifier is a type of differential amplifier that has been outfitted with input buffer amplifiers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in measurement and test equipment. instrumentation amplifier input pins as shown in Figure 2. The Instrumentation Amplifier (IA) resembles the differential amplifier, with the main difference that the inputs are buffered by two Op Amps.
