DS18B20-PAR Datasheet 1-wire Parasite-power Digital Thermometer

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: m o .c U 4 t e e .dalsemi. h S.

General Description

The DS18B20-PAR digital thermometer provides 9 to 12–bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points.

The DS18B20-PAR does not need an external power supply because it derives power directly from the data line (“parasite power”).

The DS18B20-PAR municates over a 1-wire bus, which by definition requires only one data line (and ground) for munication with a central microprocessor.

Key Features

  • a t interface requires only one.
  • Unique a 1-wire port pin for communication D.
  • Derives power from data line (“parasite w power”).
  • does not need a local power supply w.
  • Multi-drop capability simplifies distributed w temperature sensing.
