Pressure Sensors Transducers Procurement Notes

Verify the specific manufacturer designation, as historical records indicate transitions between Freescale Semiconductor, NXP Semiconductors, and STMicroelectronics for this part number. Confirm current availability status, as some sources list the component as discontinued or restricted. Ensure compatibility with existing SPI bus configurations and validate that the LGA-8 footprint matches your PCB layout requirements before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this component when a low-cost, absolute pressure measurement solution is required with minimal external circuitry. The integrated signal conditioning eliminates the need for separate amplifiers or ADCs. Consider the 10-bit resolution and 1 kPa accuracy for applications where high precision is not critical. Verify that the operating temperature range meets environmental demands and that the SPI interface aligns with the host controller's capabilities.

Pressure Sensors Transducers Part Context

The MPL115A1 belongs to the MPL115x family of digital barometers developed by NXP Semiconductors (formerly Freescale). This series includes variants such as the MPL115A2, which offers I²C communication instead of SPI. These sensors are designed to replace traditional analog pressure sensors by providing calibrated digital outputs directly, reducing system complexity and board space requirements in consumer electronics and industrial monitoring devices.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component history involves acquisitions by STMicroelectronics, but no direct equivalent replacement model is explicitly listed in the source material.
