Silicon Labs introduced a new family of high-precision temperature sensors offering industry-leading power efficiency.
Silicon Labs’ ultra-low-power Si705x temperature sensors consume only 195 nA (typical average current) when sampled once per second, which minimizes self-heating and enables multi-year coin cell battery operation. Unlike traditional digital temperature sensors, the Si705x devices maintain their accuracy across the full operating temperature and voltage ranges and offer four accuracy levels up to +/-0.3 °C. The sensors are ideal for HVAC, white goods, computer equipment, asset tracking, cold chain storage, industrial control and medical equipment. AEC-Q100-qualified versions are also available for automotive applications.
Traditional approaches to temperature sensing that use thermistors or embedded MCU temperature sensors suffer from poor accuracy and higher power consumption. Although improved accuracy can be achieved through end-of-line calibration, this technique presents additional manufacturing costs and challenges while accuracy is still susceptible to variations in power supply voltage. In contrast, the Si705x sensors’
