Hi team!

When I use the VCC=3.3，VEE=GND=0 to supply,  both of the TLV3801 out+ and TLV3801 out- are high level, as shown in figure.  What could be the cause of this？ Is there any advice?

    Hi, team! The issue has been solved. Input has to be >Vee+1.5V. When I adjust input parameter, the output can be normal. But I think this condition is in the recommended operating conditions, is this rule obligatory?

    Hi Hale,

    Thats great you were able to solve the problem. Yes, operating within the recommended operating conditions is obligatory as that is how we can warranty the behavior of the device. If you operate outside the recommended ranges, it is possible the device may work but we cannot guarantee that. Or you may see unexpected behavior on the output as you experienced.
