Analog absolute pressure sensor, 20 kPa to 550 kPa Rev. 1.2 — 3 November 2023 Product data sheet

1 General description

The FXPS7550A4S high-performance, high-precision absolute pressure sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated analog output. This sensor is ideal for many automotive applications such as manifold air pressure (MAP), turbo MAP, comfort seating, and other applications requiring operating absolute pressure ranges up to 550 kPa. The sensing element is based on NXP's high precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. It delivers highly accurate ratiometric analog readings of absolute pressure while operating from either a 3.3 V or 5.0 V power supply. 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 printed circuit board (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.

7.3 Analog output function

7.3.1 Analog output signal chain

The device provides an analog output ratiometric to the supply voltage. The analog output is enabled by default.

The non-interpolated PABS sensor data output is saturated to 10 bits and converted to an unsigned value.
The 10-bit sensor value is input into a summer clocked at 10 MHz.
The carry from the summer circuit generates a PCM output.
The PCM signal is filtered by a 2-pole active low pass filter to generate an analog signal.
