I am using a low power dual comparator (part number ALD2301A). I am trying to take some measurements on the output. I set the inverting to 2.5V and vary the non-inverting between 0V and 5V. When the non-inverting is between 0V and 2.5V, the output should read 0V, correct? When the non-inverting is between 2.6V and 5V, the output should read 5V, correct? Will this is not happening during my simple experiment. I get small voltages (mV) on the output while adjusting the non-inverting between 2.6V and 5V. Why I do not get 5V or something near it on the output? I get 0V when adjusting the non-inverting between 0V and 2.5V.
I set the power supply on the op-amp to 5V. I am not loading the output with any resistor and have not attached any resistore to the inputs of the op-amp.
I am only using one of the comparators on the chip. Nothing is hooked up to the other comparator on the chip..
Why is this happening? Am I missing something? Can anyone help me?
