VooT = [1+(RF/R1)]×(Vio) + (RF×Io). 3. Why it is necessary to calibrate all op-amp in the system periodically?
A. To maintain current drift of a system
B. To maintain output offset voltage in op-amp
C. To maintain accuracy and linearity of a system
D. None of the mentioned
Answer:A
VooT = [1+(RF/R1)]×(Vio) + (RF×Io). 3. Why it is necessary to calibrate all op-amp in the system periodically?
A. To maintain current drift of a system B. To maintain output offset voltage in op-amp C. To maintain accuracy and linearity of a system D. None of the mentioned
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.
