LPS22HB

ABSOLUTE, PEIZORESISTIVE PRESSURE SENSOR, 3.77-18.274Psi, SQUARE, SURFACE MOUNT, 2 X 2MM, 0.76MM HEIGHT, ROHS COMPLIANT, HLGA-10

The 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 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 LPS22HB 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.
