The device delivers ultra-low pressure noise with very low power consumption and operates over an extended temperature range from -40 °C to +105 °C. The ILPS22QS comprises a sensing element and an IC interface which communicates over I²C, MIPI I3CSM or SPI interfaces from the sensing element to the application and supports 1.2 V digital interface as well. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.
