MCP9804 digital temperature sensor
Microchip Technology Inc. introduce the MCP9804 digital temperature sensor . MCP9804 temperature sensor can read temperatures between -40°C and +125°C and convert it in a digital data with high accuracy (±0.25°C typically , ±1°C maximum).
The MCP9804 comes with user-programmable registers which allow user-selectable settings such as shutdown or low-power modes temperature alert and other.
The MCP9804 sensor has an industry standard 100 kHz 2-wire SMBus/I2C compatible serial interface which allow up to eight or sixteen sensors to be controlled with a single .
Main features of the MCP9804 digital temperature sensor are : high accuracy , user selectable measurement resolution ( 0.5°C, 0.25°C, 0.125°C, 0.0625°C ) , user programmable temperature limits ,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 .
