    Docket ↓
    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 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 Applications ...
