I measured the voltage of the inputs when they are left floating, it is ~1.6V.
When I connected the inputs to the outputs of amplifier, they are ~0V.
Is it right?
Thank you for considering ADI parts in your design. May I know in what application will you be using the ADCMP601? It would also be great if you could share your schematic for us to have a better picture how you are using ADCMP601 in your circuit.
When leaving the pins floating, the inputs would be in a random potential and may cause the output to swing to "0" or "1" logic depending on that random potential. I suggest trying to force a set voltage on the inputs to confirm if the comparator is working.
I used it for leading edge discriminator in Positron Emission Tomography.
Here are my schematic. The "out1" are connected to "S_in1".
If I disconnected "Out1" from "S_IN1", the voltage of 'S_IN1" is ~1.6V. When I connected them together, and keep R6, the voltage is ~0.3V. When I delete R6 and change C1 to 0 ohm resistor, the voltage is ~0V (the output of the amplifier).
