Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'A' confirms the absolute pressure type and 30 PSI range. Confirm the 'M' variant indicates the digital I2C output rather than analog or other interfaces. Ensure the 14-SOIC package matches your PCB footprint requirements. Check moisture sensitivity level handling procedures during assembly. Validate that the operating voltage range aligns with your system power supply.

Pressure Sensors Transducers Selection Notes

Choose this component when a compact, digitally interfaced absolute pressure sensor is required. The 14-bit resolution provides precise data acquisition for low-pressure applications. The I2C interface simplifies microcontroller connectivity compared to analog outputs. Consider the wide operating temperature range for harsh environment deployment. Evaluate the cost-effectiveness relative to calibrated analog alternatives.
