MAX31820 Datasheet 1-wire Ambient Temperature Sensor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX31820 1-Wire Ambient Temperature Sensor General.

General 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.

Key Features

  • Unique 1-Wire Interface Requires Only One Port Pin for Communication.
  • Each Device has a Unique 64-Bit Serial Code Stored in On-Board ROM.
  • Multidrop Capability Simplifies Distributed Temperature-Sensing.
