DS1822 Digital Thermometer

DS1822 Digital Thermometer Series Datasheet

The DALLAS SEMICONDUCTOR (MAXIM) DS1822-PAR digital thermometer provides 9- to 12-bit centigrade temperature measurements and has an alarm function with nonvolatile (NV) user-programmable upper and lower trigger points. The DS1822-PAR does not need an external power supply because it derives power directly from the data line (“parasite power”). The DS1822-PAR communicates over a 1-Wire bus, which by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +100°C and is accurate to ±2.0°C over a range of -10°C to +85°C.
