Various circuits design electronic projects

Using LTC2990 integrated circuit you can design a very simple monitoring system 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.
