Description

General part information

LTC2990 Series

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 accuracyor any combination of the three.ApplicationsTemperature MeasurementSupply Voltage MonitoringCurrent MeasurementRemote Data AcquisitionEnvironmental Monitoring
