Silicon Labs Si7057 Series Digital Temperature Sensor, Voltage Output, Surface Mount, I2C, ±0.35°C, 6 Pins

Si705x Digital Temperature Sensors are composed of a band-gap temperature sensor and a 14-bit ADC. They have been developed with power efficiency in mind featuring minimal self-heating, longer coin-cell battery lifespan and accuracy stability across all temperature and voltage ranges. They are also cost-effective, requiring no calibration and use battery power.
The Si705x sensors are ideal for HVAC, white goods, computer equipment, asset tracking, cold chain storage, industrial control and medical equipment applications.
