Suppose you put a 5V voltage source in one terminal and 2V voltage source in the other. What happens then?
If the input voltage exceeds the supply voltage of an op amp, it can cause the op amp to saturate, meaning the output voltage will remain at the maximum or minimum voltage level regardless of the input voltage. This can result in distortion or damage to the op amp.
If the input voltage is lower than the supply voltage of an op amp, the output voltage will also be limited by the supply voltage. This can result in a smaller output voltage than expected, and may also cause distortion if the input voltage is too low.
If the input voltage is equal to the supply voltage of an op amp, the output voltage will be at the maximum or minimum voltage level, depending on the polarity of the input voltage. However, this can also lead to instability and oscillation in the op amp's output if the supply voltage is not well regulated.
If the supply voltage is not well regulated, it can cause the op amp to have inconsistent or unpredictable behavior. This can result in inaccurate output voltages and potential damage to the op amp.
Forcing a different voltage into an op amp can result in a variety of dangers, including damaging the op amp, causing distortion in the output signal, and creating unstable or oscillating behavior. It is important to ensure that the input and supply voltages are within the specified range for the op amp to function properly and safely.
