    +Description
    +-----------
    +
    +The MAX127 is a multirange, 12-bit data acquisition system (DAS) providing
    +8 analog input channels that are independently software programmable for
    +a variety of ranges. The available ranges are {0,5V}, {0,10V}, {-5,5V}
    +and {-10,10V}.
    +
    +The MAX127 features a 2-wire, I2C-compatible serial interface that allows
    +communication among multiple devices using SDA and SCL lines.
    +
    +Sysfs interface

    + ============== ==============================================================
    + in[0-7]_input The conversion value for the corresponding channel.
    + RO
    +
    + in[0-7]_min The lower limit (in Volt) for the corresponding channel.
    + For the MAX127, it will be adjusted to -10, -5, or 0.
    + RW
    +
    + in[0-7]_max The higher limit (in Volt) for the corresponding channel.
    + For the MAX127, it will be adjusted to 0, 5, or 10.
