Pressure Sensors Transducers Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration. Confirm that the HLGA-10 package dimensions align with the target PCB footprint. Ensure the selected variant meets the required humidity sensitivity level (MSL 3) for the intended manufacturing process. Cross-reference the datasheet revision to confirm interface compatibility and electrical characteristics before finalizing procurement orders.

Pressure Sensors Transducers Selection Notes

Select this model when low power consumption and high precision are critical for battery-operated devices. The LPS22CHTR provides superior noise performance compared to standard variants, making it suitable for sensitive altitude measurements. Consider the 10-pin HLGA package for space-constrained designs requiring surface mount technology. Verify that the 24-bit resolution meets the system's data processing requirements.

Pressure Sensors Transducers Part Context

The LPS22CHTR belongs to STMicroelectronics' LPS22 series of MEMS pressure sensors. This family includes variants like the LPS22HB and LPS22DF, which share similar form factors but differ in accuracy and power specifications. The LPS22CHTR is positioned as a high-performance option within this lineup, offering enhanced noise reduction while maintaining the ultra-compact profile typical of the series.

Pressure Sensors Transducers Replacement Considerations

The LPS22HHTR is documented as a parameter-equivalent alternative. Both components share the same pressure range, package type, and interface options. Verify that the accuracy and noise specifications of the substitute meet the original design requirements before implementing any cross-compatibility changes.
