What is meant by the term “op-amp input offset voltage”?
The output voltage of the op-amp minus its input voltage
The difference between the output voltage of the op-amp and the input voltage required in the immediately following stage
The differential input voltage needed to bring the open loop output voltage to zero✓پاسخ درست
The potential between the amplifier input terminals of the op-amp in an open loop condition
توضیح
Real op-amp input stages are never perfectly matched, so tying both inputs together does not give exactly zero at the output. The input offset voltage is the small differential voltage that has to be applied between the inputs to drive the open-loop output back to zero.
