APPLICATION OF DUAL MATCHED OPERATIONAL common-mode and power supply rejection ratios. Note also AMPLIFIERS that the impedances of each input, both common-mode and differential-mode, are extremely high, an important feature ADVANTAGES OF DUAL MATCHED OPERATIONAL not possible with single operational amplifier circuits. ‘AMPLIFIERS Common-mode rejection can be made exceptionally high; Dual matched operational amplifiers provide a powerful tool this is very important in instrumentation amplifiers where for the solution of some difficult circuit design problems. errors due to large common-mode voltages can be far greater Circuits include true instrumentation amplifiers, extremely _— than errors due to noise or drift with temperature. For exam- low drift, high common-mode rejection DC amplifiers, low ple, consider the case of two op amps, each with 80dB DC drift active filters, dual tracking voltage references, and (1002V/V) CMRR. If the CMRR of one device is + 100uW/V many other demanding applications.

This procedure is used during factory testing of the devices. The same results are obtained by trimming side B to match side A or by nulling a ° each side individually.
