MPX5500DP

Pressure Sensors Transducers Overview

The NXP MPX5500DP is a monolithic silicon piezoresistive differential pressure sensor with an integrated unibody design. It features dual axial barbed ports for fluid connection and provides an analog voltage output ranging from 0.2 V to 4.7 V. The device operates on a supply voltage between 4.75 V and 5.25 V, consuming approximately 7 mA of current. It supports a maximum operating pressure of 500 kPa (72.5 psi) with a maximum overpressure limit of 2000 kPa. The sensor maintains an accuracy of ±2.5% and functions within a temperature range of -40°C to +125°C.

Pressure Sensors Transducers Procurement Notes

Verify the manufacturer source carefully, as listings may attribute this part to STMicroelectronics or Freescale due to historical corporate transitions. Confirm the package type matches the required mounting style, as some distributors list through-hole variants while others specify surface mount. Ensure the specific suffix corresponds to the desired port configuration and calibration curve before ordering.

Pressure Sensors Transducers Selection Notes

Select this component when a high overpressure margin is required alongside a standard 500 kPa operating range. The integrated unibody design simplifies assembly by eliminating external diaphragms. Consider the ±2.5% accuracy specification against system requirements. Verify that the analog voltage output interface is compatible with the downstream microcontroller or amplifier input impedance.

Pressure Sensors Transducers Part Context

The MPX5500DP belongs to the MPX5500 series of piezoresistive pressure sensors originally developed by Motorola and later acquired by Freescale Semiconductor. Following the acquisition of Freescale by NXP Semiconductors, these parts are now distributed under the NXP brand. This series represents a legacy line of silicon pressure transducers known for robust mechanical designs and wide temperature stability.
