3 Description 
GXT110 is a high-precision digital temperature sensor optimized for human body temperature measurement. It can achieve 16-bit (0.0078125°C) temperature output without any external temperature sensing unit, and has a temperature measurement error of less than ±0.1°C in the range of 30℃~45℃. 
GXT110 supports two packaging forms: WLCSP-4 and MCLGA-4. The former is extremely small and suitable for applications with extremely limited space; the latter can conduct heat rapidly and is designed for measuring the surface temperature of human skin. 
GXT110 supports single-line communication and can mount up to 16 slaves, requiring only a single signal line to obtain temperature output.
