9.2.1.2.7 Passive Component Tolerances and Materials

Resistors R1, R2, R3, R4, R5, R6, and R7 directly affect the accuracy of the circuit. To meet the unadjusted accuracy goals of 0.2%, the resistors used are 0.1%. Select 0.1% resistors for the construction of the difference amplifier circuit to provide a common-mode rejection ratio (CMRR) of at least 60dB.
