3. Chip Overview
The GX112 is a digital temperature sensor with high-accuracy, low-power, and NTC/PTC thermistor replacements. It can be used for extended temperature measurement in communication, computer, consumer electronics, environmental, industrial and instrumentation applications. The GX112 provides ≤±0.5°C temperature accuracy with good temperature linearity over the normal operating range of -40°C to +125°C. The GX112 can provide extended temperature measurement mode, extending the temperature measurement range from -55°C to +150°C. 
The rated working voltage range of the GX112 is 1.4V~5.5V, and the maximum quiescent current in the entire working rage is 10µA (temperature measurement frequency 4Hz). The on-chip 12-bit ADC offers resolutions down to 0.0625°C. 
The GX112 adopts SOT563 / DFN6 package of 1.6mm × 1.6mm, is compatible with SMBus and I2C interface, and allows up to four devices on one bus. The device also features an SMBus alert function.
