SILICON LABS SI7055-A20-IM

Accuracy maintained over the entire operating temperature and voltage range. Low Power Consumption: 195 nA average current @ 1 Hz sample rate, 14-bit resolution. Factory calibrated. I²C interface. 3x3 mm DFN package. 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 14-bit 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 HVAC/R and asset tracking to industrial and consumer platforms.
