MAX31825
Overview
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.
- 1-Wire Interface Requires Only One Port Pin for Communication
- Unique 64-bit Serial Code Stored in an On-Board ROM
- External Resistor Selects Address for Location Identification
- Can Be Powered From Data Line
- Power Supply Range is 1.6V to 3.6V (External Power), 2.3V to 3.6V (Parasite Power)
- Measures Temperatures from -45°C to +145°C
- Better Than ±1°C Accuracy from 0°C to +70°C
- Better Than ±1.75°C Accuracy from -45°C to +145°C
- Alarm Output for Detection of Temperature Faults
- Temperature Resolution is Selectable from 8 to 12 Bits
