Pin Assignments Top View Description The 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 analog-to-digital converter with up to 14bit resolution, signal processing, calibration data, and an I2C interface.
The patented use of novel signal processing and analog 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.
The Si705x devices are available in a 3x3 mm DFN package, and the industry-standard I2C interface can operate at up to 400 kHz.
Requiring just 195 nA of average current when sampled once per second, the Si705x can operate for several years with just a single coin cell battery.
The Si705x devices offer an accurate, low-power, factory-calibrated digital solution ideal for measuring temperature in applications ranging from HV...
