LPS22HHQTR

Pressure Sensors Transducers Overview

The LPS22HHQTR is a high-performance MEMS nano pressure sensor functioning as a digital output barometer. It features an ultra-compact piezoresistive absolute pressure sensing element with an integrated IC interface communicating via I²C, SPI, or MIPI I3C SM. The device operates within an absolute pressure range of 260 to 1260 hPa (3.77 PSI to 18.27 PSI). It provides 24-bit pressure data output with an accuracy of 0.5 hPa and low noise of 0.65 Pa. Supply voltage ranges from 1.7 V to 3.6 V, with current consumption down to 4 μA. It includes embedded temperature compensation and FIFO.
