LPS22HH屬于傳感器變送器的壓力傳感器、變送器。由意法半導體集團制造生產(chǎn)的LPS22HH壓力傳感器、變送器壓力傳感器或變送器用于檢測并響應器件上作用力的存在或量變。壓力類型有絕對壓力、復合壓力、差壓、表壓、密封表壓、開關、真空和排氣表壓，工作壓力為 -100 PSI (-689.48 kPa) 至 20000 PSI (137895.15 kPa)。

描述 Description

The LPS22HH is an ultra-compact piezoresistive

absolute pressure sensor which functions as a

digital output barometer. The device comprises a

sensing element and an IC interface which

communicates through I2C, MIPI I3CSM or SPI

from the sensing element to the application.

The sensing element, which detects absolute

pressure, consists of a suspended membrane

manufactured using a dedicated process

developed by ST.

The LPS22HH is available in a full-mold, holed

LGA package (HLGA). It is guaranteed to operate

over a temperature range extending from -40 °C

to +85 °C. The package is holed to allow external

pressure to reach the sensing element.
