MPX2100A

Pressure Sensors Transducers Overview

The MPX2100A is a silicon piezoresistive pressure sensor designed for absolute, gauge, and differential measurements within a 0 to 100 kPa range. It features a monolithic silicon diaphragm with integrated strain gauges and a thin-film resistor network. The device delivers a linear voltage output proportional to applied pressure. Key specifications include a supply current of 6mA, sensitivity of 0.4 mV/kPa, and an operating temperature range of -40°C to 125°C. The unit utilizes a UNIBODY4F package with four terminals.

Pressure Sensors Transducers Feature Summary

• HVAC pressure sensing applications

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix (e.g., AP, DP) against the required pressure type (absolute or differential) as the base series covers multiple configurations. Confirm package compatibility with the UNIBODY4F footprint. Note that NXP MEMS products have transitioned to STMicroelectronics; check current availability and lifecycle status before procurement planning.

Pressure Sensors Transducers Selection Notes

Select this component when a compact, calibrated silicon piezoresistive solution is needed for low-pressure ranges up to 100 kPa. Ensure the application requires absolute pressure measurement if choosing the 'A' variant. Verify that the 6mA supply current and 0.4 mV/kPa sensitivity align with the system's signal conditioning capabilities and power budget constraints.

Pressure Sensors Transducers Part Context

The MPX2100 series represents a family of silicon piezoresistive sensors from NXP (formerly Motorola/Freescale). These devices are engineered for diverse medical and industrial uses. The MPX2100A specifically addresses absolute pressure needs within the 0-100 kPa spectrum, utilizing on-chip compensation to maintain accuracy across varying temperatures.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the transition of NXP MEMS products to STMicroelectronics, consult STMicroelectronics documentation for potential equivalents.
