MAX31820PAR Overview
The MAX31820PAR 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.
MAX31820PAR Key Features
- Unique 1-Wire Interface Requires Only One Port Pin for munication
- Derives Power from Data Line (Parasite Power); No Local Power Supply Needed
- Multidrop Capability Simplifies Distributed Temperature-Sensing
