TMP1820 Overview
The TMP1820 is 1-Wire®, high-accuracy, digitaloutput temperature sensor. The accuracy is as high as ±0.1°C across the 20°C to +85°C or ±0.4°C across the 55°C to +125°C temperature range. Each device incorporates a factory-programmed 64bit unique identification number used for addressing and allows NIST traceability.
