Published:2011/8/29 1:46:00 Author:Amy From:SeekIC

Linear Technology Corporation, a worldwide designer and manufacturer of standard high performance integrated circuits, recently released LTC2990 - Quad I2C Voltage, Current and Temperature Monitor.

The features of the device including:

Measures Voltage, Current and Temperature
Measures Two Remote Diode Temperatures
±0.5°C Accuracy, 0.06°C Resolution (Typ)
±1°C Internal Temperature Sensor (Typ)
14-Bit ADC Measures Voltage/Current
3V to 5.5V Supply Operating Voltage
Four Selectable Addresses
Internal 10ppm/°C Voltage Reference
10-Lead MSOP Package

The LTC2990 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the device can be built 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.

The application of LTC2990 covers temperature measurement, supply voltage monitoring, current measurement, remote data acquisition and environmental monitoring.
