What is the use of Difference and Instrumentation Amplifier?
The discussion focuses on the differences between Difference Amplifiers and Instrumentation Amplifiers, highlighting that Instrumentation Amplifiers are specialized versions of differential amplifiers designed for precision applications. They incorporate input buffers to eliminate the need for input impedance matching, making them ideal for use in measurement and test equipment, such as quality multimeters. The precision and stability of Instrumentation Amplifiers make them essential in various high-accuracy applications.
PREREQUISITESElectronics engineers, instrumentation specialists, and anyone involved in the design or use of precision measurement equipment will benefit from this discussion.
http://en.wikipedia.org/wiki/Instrumentation_amplifier"An instrumentation (or instrumentational) amplifier is a type of differential amplifier that has been outfitted with input buffers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in measurement and test equipment.
