WebOffset has been reduced with modern manufacturing processes through increased matching and improved package materials and assembly." Note that input offset voltage and output offset voltage are ... Webthe input offset voltage by about +/-15mV. Input Offset Current: Earlier we stated that the input impedance of the ideal op-amp is infinite and that no current entered the input pins. Well, in the real world some current does enter the inputs. In this case the difference between the two input currents is about 20nA (200nA worst case at 25C).
