MPL3150A2

Pressure Sensors Transducers Overview

The MPL3150A2 is a compact, piezoresistive absolute pressure sensor featuring an I²C digital interface. It operates within a wide range of 50 kPa to 150 kPa. The device integrates full temperature compensation, unit conversion, and digital signal processing internally to deliver ready-to-use 20-bit pressure values. It supports supply voltages between 1.95 V and 3.6 V and functions in temperatures from -40°C to +85°C. Packaged in an LGA-8 format, it provides calibrated data for precise measurement applications.

Pressure Sensors Transducers Procurement Notes

This component is officially discontinued and no longer in active production by NXP USA Inc. Verify end-of-life status with authorized distributors before integration. Sourcing new units may be limited to existing stock or third-party suppliers. Ensure compatibility with replacement components if redesigning the circuit.

Pressure Sensors Transducers Selection Notes

Select this part only if legacy support for the MPL3115A2 series is required. Note that the device is obsolete; alternative sensors with similar I²C interfaces and pressure ranges should be evaluated for new designs. Confirm voltage compatibility with the 1.95 V to 3.6 V operating range and ensure the LGA-8 package fits the PCB layout constraints.

Pressure Sensors Transducers Part Context

The MPL3150A2 belongs to the MPL31xxA2 family of absolute pressure sensors manufactured by NXP USA Inc. It shares architectural similarities with the MPL3115A2 but offers specific calibration ranges. Both parts are now discontinued, representing a legacy solution for low-power, high-precision pressure measurement in consumer and industrial electronics.

Pressure Sensors Transducers Replacement Considerations

NXP has officially discontinued the MPL3150A2. No direct substitute part numbers are confirmed in public documentation. Engineers must evaluate alternative pressure sensors from other manufacturers or newer NXP products with compatible I²C interfaces and pressure ranges.
