Product data sheet
1 General description
The FXPS7550D4 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 FXPS7550D4 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 20 kPa to 550 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.
