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. 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 little current.
Si705x sensors are fully factory-calibrated and available in a 3x3 mm DFN package. The industry-standard I2C interface can operate at up to 400 kHz. Requiring just 195nA of average current when sampled once per second, Si705x sensors can operate for several years with just a single coin cell battery.
