If the effect of VOs(input offset voltage) is nulled at room temperature (250C). The circuit is to operate at a temperature in the range 0°C to 75°C and the temperature coefficient of VOS is 10 μV/°C?

Consider an inverting amplifier with a nominal gain of 1000 constructed from an op amp with an input offset voltage of 3 mV and with output saturation levels of ±10 V. If the effect of VOs(input offset voltage) is nulled at room temperature (250C). The circuit is to operate at a temperature in the range 0°C to 75°C and the temperature coefficient of VOS is 10 μV/°C? Correct Answer 9.5 mV

Since the effect is nullified at 25oC, the peak that can be sent now is given by 10 – (75-25) X 0.1 mV.
