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 …
