The Infineon KP216H1416 is a board-mount absolute pressure sensor from the XENSIV family, delivering an amplified, temperature-compensated analog voltage output proportional to absolute pressure. It covers a 7.25 PSI to 21.76 PSI (50 kPa to 150 kPa) range.
The analog output swings from 0.5 V at the low end of the pressure range to 4.5 V at the high end, referenced to a 4.5 V to 5.5 V supply. That ratiometric relationship means the ADC reference should track the sensor supply to avoid offset errors across the full pressure span. The ±0.35 PSI (±2.38 kPa) accuracy holds over the rated temperature range, so the system-level error budget can allocate the rest of the margin to the ADC, reference drift, and mechanical hysteresis in the pressure port.
No pin-compatible second source is documented in the Infineon XENSIV family — the analog output and absolute pressure type are specific to this variant, so a direct drop-in substitution is not guaranteed without re-validating the output transfer function.
