GX18B20 GXCAS Technology 18B20 Programmable Resolution 1- Wire Digital Thermometer DESCRIPTION The GX18B20 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 GX18B20 communicates over a 1-Wire bus that 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 +125°C and is accurate to ±0.4°C over the range of -10°C to +70°C. In addition, the GX18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.
