Absolute pressure sensing for 5 V analog interfaces
The NXP MPXH6101A6U is a piezoresistive absolute pressure sensor in the MPXH6101A series, delivering a ratiometric 0.2 V to 5 V analog output proportional to the applied absolute pressure from 2.18 PSI to 15.23 PSI (15 kPa to 105 kPa). The 0.2 V to 5 V output span maps directly onto a 5 V ADC reference — no external level shifting needed for a 0-5 V input range, though the 0.2 V offset at zero pressure means the usable ADC code range starts at about 4% of full scale.
SOIC-8 footprint and supply rail compatibility
The port style is listed as No Port — this is a surface-mount device with no barb or tube fitting; pressure is applied via the top of the package through a gel or epoxy interface, typical for board-mounted absolute sensors where the reference vacuum is sealed inside the package.
