LTC2990
Quad I2C Voltage, Current
and Temperature Monitor
FEATURES DESCRIPTION Measures Voltage, Current and Temperature
nn Measures Two Remote Diode Temperatures
nn ±0.5°C Accuracy, 0.06°C Resolution (Typ)
nn ±1°C Internal Temperature Sensor (Typ)
nn 14-Bit ADC Measures Voltage/Current
nn 3V to 5.5V Supply Operating Voltage
nn Four Selectable Addresses
nn Internal 10ppm/°C Voltage Reference
nn 10-Lead MSOP Package nn The LTC®2990 is used to monitor system temperatures,
voltages and currents. Through the I2C serial interface,
the device can be configured to measure many combinations 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. nn All registered trademarks and trademarks are the property of their respective owners. nn APPLICATIONS …
