DESCRIPTION

The DS1825 digital thermometer provides 9 to 12-bit centigrade temperature measurements and has an alarm

function with NV user-programmable upper and lower trigger points. The DS1825 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 M0.5LC over the range of -10°C to +85°C. In

addition, the DS1825 can derive power directly from the data line (“parasite power”), eliminating the need for an

external power supply.
