FXPS7115D4

Digital absolute pressure sensor, 40 kPa to 115 kPa

Rev. 3 — 5 December 2019

Product data sheet

1 General description

The FXPS7115D4 high-performance, high-precision barometric absolute pressure (BAP)

sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS)

device coupled with a digital integrated circuit (IC) producing a fully calibrated digital

output.

The sensor is based on NXP's high-precision capacitive pressure cell technology. The

architecture benefits from redundant pressure transducers as an expanded quality

measure. This sensor delivers highly accurate pressure and temperature readings

through either a serial peripheral interface (SPI) or an inter-integrated circuit (I²C)

interface. The FXPS7115D4 uses either a 3.3 V or 5.0 V power supply. Furthermore,

the sensor employs an on-demand digital self-test for the digital IC and the MEMS

transducers.

The sensor operates over a pressure range of 40 kPa to 115 kPa and over a wide

temperature range of −40 ºC to 130 ºC.

The sensor comes in an industry-leading 4 mm x 4 mm x 1.98 mm, restriction of

hazardous substances (RoHS) compliant, high power quad flat no lead (HQFN)

package^[1]suitable for small PCB integration. Its AEC-Q100^[2]compliance, high

accuracy, reliable performance, and high media resistivity make it ideal for use in

automotive, industrial, and consumer applications.
