Optional trimming of output offset voltage
Webbipolar op amps, offset and drift are closely correlated where for each one millivolt of offset voltage at 25°C, one can expect to get about 3.3 µV/C of offset drift; Vos_drift = Vos(T) / (T + 273°C). This means that trimming the input offset voltage to zero assures that drift is also close to zero. However, when it http://class.ece.iastate.edu/rlgeiger/Randy505/lectures/EE%20505%20Lect%2011%20Spring%202424.pdf
