MAX31825 1-Wire® Temperature Sensor With ±1ºC Accuracy General Description The MAX31825 temperature sensor provides 8-bit to 12-bit Celsius temperature measurements with better than ±1°C accuracy from 0°C to +70°C and ±1.
75°C from -45°C to +145°C.
The sensor communicates over a 1-Wire® bus that, by definition, requires only one data line (and ground) for communication with a microcontroller.
In addition, the sensor can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.
Each sensor has a unique 64-bit serial code, which allows multiple MAX31825 ICs to reside on the same 1-Wire bus.
In addition, it includes two address input pins that, using an external resistor and pin-strapping, allow one of 64 different addresses to be selected to identify each sensor's physical location.
Therefore, it is simple to use one microprocessor to control many devices distributed over a large area.
The MAX31825 is available in a 6-bump WLP package.
The power supply voltage range is from 1.
6V to 3.
6V for external power supplies, and from 2.
3V to 3.
6V for parasite power.
The operating temperature range is from -45°C to +145°C.
