Jung, Walter. An IC instrumentation amplifier typically contains closely matched laser-trimmed resistors, and therefore offers excellent common-mode rejection. For this, an instrumentation amplifier is used instead of an Opamp. Instrumentation amplifiers are needed in nearly every field of electronics, particularly in the test and measurement industry. Get giftable tech Shop now. Its clever design allows U1 and U2 operational amplifiers to share the current through the feedback resistors R5, R6 and RG.
