MAX31820 Description
The MAX31820 ambient temperature sensor provides 9-bit to 12-bit Celsius temperature measurements with ±0.5°C accuracy over a +10°C to +45°C temperature range. Over its entire -55°C to +125°C operating range, the device has ±2.0°C accuracy. The device municates over a 1-Wire® bus that, by definition, requires only one data line (and ground) for munication with a central microprocessor.
MAX31820 Key Features
- Unique 1-Wire Interface Requires Only One Port Pin for munication
- Each Device has a Unique 64-Bit Serial Code Stored in On-Board ROM
- Multidrop Capability Simplifies Distributed Temperature-Sensing
