 3 . Chip Overview
The GXT310 is a fully integrated digital tempera-ture sensor optimized for human body temperature measurement. 
The GXT310 requires no external components to sense the temperature. The op-chip 16-bit ADC offers resolution down to 0.0078℃. Each chip is specially calibrated for ±0.1°C (max.) accuracy over +30°C to +45°C range in factory before shipment to customers, eliminating the need for users to make any additional adjustments for temperature output. 
The GXT310 features SMBus and I2C interface with speed up to 1MHz (2.3MHz at high-speed mode), and allows up to eight devices on the same bus. The GXT310 has a 3-digit built-in address, which is distin-guished by the last digit of the part number.
