Dual full-scale, absolute digital output barometer with embedded Qvar electrostatic sensor

STMicroelectronics ILPS22QS Absolute Digital Output Barometer is an ultra-compact piezoresistive absolute pressure sensor that operates as a digital output barometer. The ILPS22QS supports dual full-scale up to user-selectable 4060hPa. The ILPS22QS features ultra-low pressure noise with very low power consumption.

The STM ILPS22QS Absolute Digital Output Barometer combines a sensing element and an IC interface that communicates over I²C, MIPI I3CSM, or SPI interfaces from the sensing element to the application. The sensing element that detects absolute pressure consists of a suspended membrane manufactured using a dedicated process developed by ST.

The ILPS22QS is offered in a full-mold, holed LGA package (HLGA) and operates over an extended temperature range from -40°C to +105°C. The LGA package is holed to allow external pressure to reach the sensing element.
