MAX31826 Datasheet 1-wire Digital Temperature Sensor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here to ask about the production status of specific part numbers.

General Description

The MAX31826 digital thermometer provides 12-bit temperature measurements and municates over a 1-Wire® bus that by definition requires only one data line (and ground) for munication with a central microcontroller.

It has a -55°C to +125°C operating temperature range and is accurate to ±0.5°C over the -10°C to +85°C range.

In addition, the device can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.

Key Features

  • Unique 1-Wire Interface Requires Only One Port Pin for Communication.
  • Integrated Temperature Sensor and EEPROM Reduce Component Count.
  • Measures Temperatures from -55°C to +125°C (-67°F to +257°F).
  • ±0.5°C Accuracy from -10°C to +85°C.
  • 12-Bit Temperature Resolution (0.0625°C).
  • 1Kb EEPROM Can Be Locked to Prevent Further Writes.
  • Multidrop Capability Simplifies Multisensor Systems.
  • Each Device Has a Unique 64-Bit Serial Code.
