LPS22HBTR

Pressure Sensors Transducers Overview

The LPS22HBTR is an ultra-compact piezoresistive absolute pressure sensor functioning as a digital output barometer. It features a sensing element and IC interface communicating via I2C or SPI. The device operates within a pressure range of 260 to 1260 hPa (26 kPa to 126 kPa) with a resolution of 24-bit for pressure data and 16-bit for temperature data. Supply voltage ranges from 1.7 V to 3.6 V, with current consumption down to 3 μA. Output data rates are configurable from 1 Hz to 75 Hz. Accuracy is specified at 100 Pa. The package is HLGA-10, operating between -40 °C and +85 °C.

Pressure Sensors Transducers Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions adhere to recommended humidity limits to prevent package degradation. Cross-reference datasheet revisions to confirm parameter consistency for production integration.

Pressure Sensors Transducers Selection Notes

Select this model when high accuracy and low power consumption are critical for battery-operated devices. The HLGA-10 package suits surface-mount applications requiring minimal footprint. Consider the LPS22HHTR variant if higher precision is required, or the obsolete LPS225HBTR for legacy compatibility. Evaluate interface requirements for I2C or SPI support during system architecture planning.
