Tuotteen yleiskatsaus

DC1338B demonstration circuit is designed to allow easy evaluation of the LTC2990 and may be connected directly to the target application's analog signals while using the DC590 USB serial controller board and supplied software to measure performance. The LTC2990 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.
