Has anyone used the MAX1238 AD converter ?

Because I'm not sure if my code is wrong or if I damaged the IC when soldering.

    Now I have done some highly advanced testing including hot melt adhesive and wood.
    I had a spare IC that works just fine.
    And I am fairly convinced that the IC was damaged when soldering it.

    Well the first was probably damaged from soldering.
    But there is still a strange behavior.
    “Channel 0” seams to work but other channels gives strange values.
    (about half the value and large fluctuations)
    And other channels seams to react on signals on channel0.

    Does anyone have any experience with this IC ?

    (edit)Well the first IC seams to work now. Probably was a human error. But I have the same strange behavior from both IC.

    Problem solved.
    It was human error after all. When I thought I was reading a single channel I was actually scanning channels. (one should not read manuals when tired)
