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癈 to +125癈 and is accurate to ?.5癈 over the range of -10癈 to +85癈. In
addition, the DS1825 can derive power directly from the data line (parasite power), eliminating the need for an
external power supply.
