It is possible to add some additional connections to enable the results mismatches in the chip to be significantly reduced. Using an offset null capability it is possible to reduce the level of the offset voltage significantly.
To incorporate an offset null capability within the op amp, a number of different actual circuits can be adopted. The op amp offset null circuitry adds a balance capability to the input circuitry
