    16-Lead MSOP Package APPLICATIONS n n n n n The LTC®2991 is used to monitor system temperatures,
    voltages and currents. Through the I2C serial interface, the
    eight monitors can individually measure supply voltages
    and can be paired for differential measurements of current sense resistors or temperature sensing transistors.
    Additional measurements include internal temperature
    and internal VCC. The internal 10ppm reference minimizes
    the number of supporting components and area required.
    Selectable address and configurable functionality give the
    LTC2991 flexibility to be incorporated in various systems ...
