Microchip | MCP9808T-E/MS

The MCP9808 digital temperature sensor converts temperatures between −20 °C and +100 °C to a digital word with ±0.5 °C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications. The registers allow user-selectable settings such as Shutdown or low-power modes and the specification of temperature Event and Critical output boundaries.
