MPL115A2

Pressure Sensors Transducers Overview

The MPL115A2 is an absolute pressure sensor manufactured by NXP USA Inc., designed for board mount applications with a digital I2C output. It targets low-cost barometric measurement applications, offering precision and low power capability in a small form factor. The device operates within an absolute pressure range of 7.25PSI to 16.68PSI (50kPa to 115kPa). Key electrical parameters include a typical operating supply voltage of 3.3V and an operating temperature range from -40°C to 105°C. The maximum overload pressure is specified at 1000KPa. The component utilizes an 8-TLGA package type.

Pressure Sensors Transducers Procurement Notes

Verify the current status of the MPL115A2 as it may be listed as obsolete in some distributor catalogs. Confirm the specific package variant (e.g., T1 suffix) matches the design requirements. Ensure the I2C address configuration aligns with the target system bus architecture. Check for availability of evaluation kits such as KITMPL115A2I2C for prototyping validation before finalizing procurement quantities.

Pressure Sensors Transducers Selection Notes

Select the MPL115A2 when a cost-effective, absolute pressure sensor with digital output is required. It is suitable for applications needing a pressure range of 50kPa to 115kPa. Consider its I2C interface compatibility and 3.3V operation. The wide temperature range supports industrial and outdoor environments. Evaluate against alternatives if higher pressure ranges or different interfaces are needed.

Pressure Sensors Transducers Part Context

The MPL115A2 belongs to the MPL115 series of digital barometric sensors from NXP Semiconductors.
