MPL115A2T1

Pressure Sensors Transducers Overview

The MPL115A2T1 is an absolute pressure sensor featuring a digital I2C output, designed for cost-effective barometric measurement applications. It integrates a MEMS pressure sensor with conditioning circuitry and an ADC within a compact 8-pin LGA package. The device operates within an absolute pressure range of 50 kPa to 115 kPa (7.25 PSI to 16.68 PSI). It supports supply voltages from 2.375 V to 5.5 V and functions across a temperature range of -40°C to +105°C. The sensor provides high precision with an accuracy of 1 kPa and utilizes a 10-bit resolution for data output.

Pressure Sensors Transducers Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm the specific tape-and-reel packaging configuration matches your assembly requirements. Check for obsolescence notices as part status may vary by region. Ensure voltage levels on the I2C bus are compatible with the 2.375 V to 5.5 V operating range. Validate that the 8-LGA package footprint aligns with your PCB design guidelines before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this component when a digital I2C interface is preferred over SPI for board space constraints. Choose the MPL115A2T1 for applications requiring absolute pressure measurement within the 50-115 kPa range. Consider its wide operating temperature range for environments subject to thermal variation. Opt for this sensor when low power consumption is critical for battery-operated devices. Ensure the application does not require higher resolution than 10 bits or different pressure ranges.
