Si705x digital temperature sensors offer industry-leading low power consumption and high accuracy across the entire operating voltage and temperature range. These monolithic CMOS ICs feature a band-gap temperature sensor element, an analogue-to-digital converter with up to 14bit resolution, signal processing, calibration data, and an I2C interface. The patented use of novel signal processing and analogue design enables the sensors to maintain their accuracy over a wide temperature and voltage range, while consuming very little current. The temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required. Target applications include HVAC/R, thermostat, white goods, computer equipment, portable consumer devices, asset tracking, cold chain storage, battery protection, industrial controls and medical equipment.
