I am trying to observe the output of a comparator for small differential input voltages of -3mV to 3mV. I want to verify how accurate my comparators are.
I tried using a power supply, by setting the non-inverting to 2.5V and adjusting the inverting until I measure a voltage difference of millivolts, but the measurments are not steady. I probally will need a more precision voltage supply for this.
I was thinking of using potentiometers to adjust the non-inverting and inverting inputs until I get stable differential input millivolts. Will this work? Have anyone else tried this. I am using ALD2301A for my comparators.
Thanks in advance
