The matching of AMPLIFIERS CMRR increases the effective CMRR when used as an Dual matched operational amplifiers provide a powerful tool instrumentation input stage. for the solution of some difficult circuit design problems. Circuits include true instrumentation amplifiers, extremely low drift, high common-mode rejection DC amplifiers, low vy DC drift active filters, dual tracking voltage references and many other demanding applications. These designs ail 3 require good matching between two operational amplifiers. [ 20kse The adjacent circuit, a differential-in, differential-out ampli- O “4 fier, shows how errors can be reduced. Assuming the Hy fo | resistors used are matched, the gain of each side will be Ls . identical; if the offset voltage of each amplifier is matched, = 4 | o then the net differential voltage at the amplifiers output will ° be zero. Note that the output offset error of this amplifier is iweur nota function of the offset voltage of the individual amplifiers, _ n ourPuT. * but only a function of the difference between the amplifiers’ ° 6 . offset voltages. This error-cancellation principle holds for a RZ 0 [=> © number of input-referred error parameters — offset voltage, be | offset voltage drift, inverting and noninverting bias currents, 7 common-mode and power supply rejection ratios. Note also na that the impedances of each input, both common-mode and _ differential-mode, are extremely high, an important feature not possible with single operational amplifier circuits. Common-mode rejection can be made very high; this is POWER SUPPLIES especially important in instrumentation amplifiers where The V+ supply terminals are completely independent and errors due to large common-mode voltages can be far greater may be powered by separate supplies if desired (this than errors due to noise or drift with temperature. approach, however, would sacrifice the advantages of the For example, consider the case of two op amps, each with power supply rejection ratio matching).
