Product Description FST Series DS18B20 Programmable Resolution 1 Wire Digital Temperature SensorThe DS18B20 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 DS18B20 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 ±0.5°C over the range of-10°C to +85°CParameterTemperaturePower Supply3.0-5.5VSensorDS18B20Measurement Range-55oC - +125oCAccuracy±0.5oC Accuracy from -10oC to +85oC±2oC Accuracy from -55oC to +125oCWork Current1.5mAStandby Current1uAOutput Pin Sink Current4mA (@VI/O=0.4V)ResponseConverts temperature to 12-bit digital word in 750 ms (max.)OutputOpen-drain 1-Wire interface pin.Drift±0.2°C on a 1000h stress test at +125°C with VDD= 5.5VFlexible customize the product specifications and shape to match your applications.1.
