Explanation: In practice, the output offset voltage in all op-amp circuit will change with time. Therefore, to maintain the desired accuracy and linearity of a system, it is necessary to calibrate all op-amps in that system periodically. 4. Determine the maximum possible change in output offset voltage after 3 month if the LH0041C op-amp is initially nulled and room temperature, voltage across terminal, +Vcc & -Vee remain constant.
A. △VooT = 456.78mv
B. △VooT = 3.452mv
C. △VooT = 21.1mv
D. None of the mentioned
