18B20 Datasheet (Maxim Integrated) - Programmable Resolution 1-Wire Digital Thermometer

18B20, Programmable Resolution 1-Wire Digital Thermometer

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

The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communicat
