MPL3115A2R1

Pressure Sensors Transducers Overview

The MPL3115A2R1 is a compact, piezoresistive absolute pressure sensor manufactured by NXP USA Inc. It features an I2C digital interface and operates within an absolute pressure range of 20 kPa to 110 kPa (7.25 PSI to 15.95 PSI). The device supports a maximum overload pressure of 500 kPa and functions with supply voltages between 1.95 V and 3.6 V, typically at 2.5 V. It utilizes an 8-pin TLGA surface-mount package and includes built-in altimetry capabilities. The sensor offers 24-bit resolution and operates across a temperature range of -40°C to 85°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'R1' indicates tape and reel packaging rather than tray packaging when sourcing components. Confirm that the part status remains active or long-term buy as availability may vary. Ensure compatibility with the required I2C bus voltage levels and check for any specific handling requirements associated with the 8-TLGA package during assembly processes.

Pressure Sensors Transducers Selection Notes

Select this component for applications requiring precise absolute pressure sensing with digital output via I2C. It is suitable for environments needing altimetry functions and low-power operation modes. Consider the 20 kPa to 110 kPa operating range and the 8-pin LGA form factor for space-constrained designs. Verify thermal performance within the specified -40°C to 85°C range for your specific application environment.

Pressure Sensors Transducers Part Context

This part belongs to the MPL3115A2 series of precision pressure sensors from NXP Semiconductors. The R1 suffix specifically denotes the tape and reel packaging variant, distinguishing it from tray-packaged versions like the standard MPL3115A2. The series is designed for compact, piezoresistive absolute pressure sensing with integrated signal conditioning and digital interfaces.

Pressure Sensors Transducers Replacement Considerations

The standard MPL3115A2 serves as a functional equivalent but differs in packaging, typically supplied in trays rather than tape and reel. When substituting, verify that the change in packaging format does not impact automated pick-and-place manufacturing processes or storage requirements.
