    MCP6001 input voltage near rail (3v3)

    Hi,
    The MCP6001 offers "rail to rail input and output".....but if the vin goes above 3.1v, then it latchs up to the 3.3v rail. Do you know where in the datasheet this is predicted?
    We are using it as a unity gain buffer......passing through the divided down Primary side HVDC Bus of a offline SMPS

    It shouldn't do that; either you're doing something wrong or your part is defective. Show your schematic.
