MAX31820PAR Datasheet Ambient Temperature Sensor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX31820PAR 1-Wire, Parasite-Power, Ambient Temperature Sensor.

General Description

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 communicates over a 1-Wire® bus that, by definition, requires only one data line (and ground) for communication with a central microprocessor.

Key Features

  • Unique 1-Wire Interface Requires Only One Port Pin for Communication.
  • Derives Power from Data Line (Parasite Power); No Local Power Supply Needed.
  • Multidrop Capability Simplifies Distributed Temperature-Sensing.
