The KP214N2611 is an Infineon XENSIV absolute pressure sensor with an operating range of 2.18 to 16.68 PSI (15 to 115 kPa). Its analog output swings from 0.18 V at the low end to 4.65 V at the high end, giving a 4.47 V span that maps linearly to the applied pressure. The ±0.65 PSI (4.50 kPa) accuracy over that span means a 2.5% FSO error budget at the top end — adequate for manifold air pressure (MAP) or barometric reference applications where the system ADC can calibrate the offset. Output is ratiometric to the supply — if the rail drifts, the pressure reading drifts with it. A precision 5 V reference on the board side eliminates that dependency.
Temperature range and signal conditioning
The integrated temperature compensation holds the accuracy across that range — without it the offset would shift by several percent over 165°C. The amplified output means you don't need an external op-amp or gain stage; the 0.18-4.65 V swing drives directly into a 5 V ADC input. The absolute pressure type means the sensor outputs a voltage proportional to the difference between the applied pressure and a sealed internal vacuum reference. For gauge or differential measurements you'd need a second sensor and external subtraction.
Housed in an 8-SMD module with the supplier package designation PG-DSOF-8-16, the KP214N2611 is a surface-mount device with SMD (SMT) tab termination. The 'No Port' port style means there is no barb or tube — pressure is applied through a hole in the package lid or via a sealed manifold that mates to the top of the module. The bulk packaging indicates loose tubes or trays, not tape-and-reel; plan for hand placement or a tube feeder if you're running high-volume pick-and-place.
