DESCRIPTION
Quad I2C Voltage, Current
and Temperature Monitor
The LTC2990 is used to monitor system temperatures,
voltages and currents. Through the I2C serial interface,
the device can be configured to measure many combi-
nations of internal temperature, remote temperature,
remote voltage, remote current and internal VCC. The
internal 10ppm/°C reference minimizes the number of
supporting components and area required. Selectable
address and configurable functionality give the LTC2990
flexibility to be incorporated in various systems needing
temperature, voltage or current data. The LTC2990 fits
well in systems needing sub-millivolt voltage resolution,
1% current measurement and 1°C temperature accuracy
or any combination of the three.
