    MCP9808
    ±0.5°C Maximum Accuracy Digital Temperature Sensor
    Features Description Accuracy:
    -±0.25 (typical) from -40°C to +125°C
    -±0.5°C (maximum) from -20°C to 100°C
    -±1°C (maximum) from -40°C to +125°C User-Selectable Measurement Resolution:
    -+0.5°C, +0.25°C, +0.125°C, +0.0625°C User-Programmable Temperature Limits:
    -Temperature Window Limit
    -Critical Temperature Limit User-Programmable Temperature Alert Output Operating Voltage Range: 2.7V to 5.5V Operating Current: 200 µA (typical) Shutdown Current: 0.1 µA (typical) 2-wire Interface: I2C™/SMBus Compatible Available Packages: 2x3 DFN-8, MSOP-8 Microchip Technology Inc.’s MCP9808 digital
    temperature sensor converts temperatures between
    -20°C and +100°C to a digital word with
    ±0.25°C/±0.5°C (typical/maximum) 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 Alert window limits and
    critical output limits. When the temperature changes
    beyond the specified boundary limits, the MCP9808
    outputs an Alert signal. The user has the option of setting
    the Alert output signal polarity as an active-low or activehigh comparator output for thermostat operation, or as a
    temperature Alert interrupt output for microprocessorbased systems. The Alert output can also be configured
    as a critical temperature output only. ...
