MPXA4115AP

Pressure Sensors Transducers Overview

The MPXA4115AP is a compact silicon pressure sensor designed for absolute air pressure sensing in altimeter or barometer applications. It measures an operating pressure range of 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI). The device features temperature compensation and calibrated output, integrating on-chip bipolar op-amp circuitry and thin film resistor networks. It provides an analog voltage output ranging from 0.2 V to 4.8 V with a supply voltage of 4.85 V to 5.35 V. The component operates within a temperature range of -40°C to 125°C and utilizes a 6-SIP module package with PC pin termination.

Pressure Sensors Transducers Procurement Notes

Verify the manufacturer designation carefully, as historical data indicates STMicroelectronics and NXP Semiconductors associations for this part number series. Confirm the specific suffix 'AP' matches the required package and termination style. Check current availability status as some listings indicate discontinued status. Ensure the application environment stays within the specified -40°C to 125°C operating temperature range. Validate that the absolute pressure requirements fall strictly between 15 kPa and 115 kPa.

Pressure Sensors Transducers Selection Notes

Select this component when absolute pressure sensing is required for altitude or barometric applications. The integrated signal conditioning eliminates the need for external amplification circuits. Ensure the system power supply aligns with the 4.85 V to 5.35 V specification. Consider the 6-SIP module package for through-hole mounting if PCB space allows. Verify that the analog voltage output interface is compatible with the downstream microcontroller or ADC input ranges.
