Maxim (DS1822+PAR) Temperature Sensor IC, ± 3°C, -55 °C, 100 °C

Temperature Sensor IC, Econo Parasite Power, Digital, ± 3°C, -55 °C, 100 °C,TO-92, 3 PinsProduct OverviewThe DS1822+PAR is an Econo 1 wire digital thermometer in 3 pin TO-92 package. Itis a digital thermometer which provides 9 to 12bit centigrade temperaturemeasurements and has an alarm function with NV user programmable upper and lowertrigger points. The DS1822 communicates over a 1 wire bus which requires onlyone data line (and ground) for communication with a central microprocessor. Ithas an operating temperature range of -55°C to +125°C and is accurate to ±2°Cover the range of-10°C to 85°C. In addition, the DS1822 can derive powerdirectly from the data line (parasite power) eliminating the need for anexternal power supply. Each DS1822 has a unique 64 bit serial code which allowsmultiple DS1822s to function on the 1 wire bus thus it is simple to use onemicroprocessor to control many DS1822s distributed over a large area.Applications that can benefit from this feature include HVAC environmentalcontrols, temperature monitoring systems, process monitoring & control systems.Supply voltage range is 3V to 5.5VConverts temperature to 12bit digital word in 750msFlexible user definable NV alarm settings with alarm search commandSoftware compatible with the DS18B20Simplifies distributed temperature sensing with multidrop capabilityReduced component count with integrated temperature sensor and interfaceRemote Sensing ApplicationsApplicationsSensing & Instrumentation, Communications & NetworkingProduct InformationIC Output Type: DigitalSensing Accuracy Range: ± 3°CSensing Temperature Min: -55°CSensing Temperature Max: 100°CSensor Case Style: TO-92No. of Pins: 3PinsSupply Voltage Min: 3VSupply Voltage Max: 5.5VProduct Range: -MSL: -
