Pressure range and output — what the analog signal tells you
The MP3H6115AC6T1 is an absolute pressure sensor from NXP, covering 2.18 to 16.68 PSI (15 to 115 kPa) with an analog voltage output that scales linearly from 0.12 V at the low end to 2.8 V at full scale. The ±1.5% accuracy spec is the combined error over the full pressure and temperature range, including offset, span, and linearity. For a 115 kPa full-scale reading, that is about ±1.7 kPa of uncertainty — enough to distinguish altitude changes of roughly 150 m at sea level, but not fine enough for a barometric altimeter requiring sub-meter resolution.
The 8.50 mm wide body and gull-wing leads match the standard SOIC-8 footprint, but the port overhang means the pick-and-place nozzle must clear the tube opening. Both the Cut Tape (CT) and Tape & Reel (TR) packaging options are available, so prototype quantities and production reels are covered from the same BOM line.
Temperature compensation and maximum pressure
The temperature-compensated feature means the sensor's output is calibrated and trimmed across the -40 to +125 °C range — no external thermistor or software correction is needed for the accuracy spec to hold. The maximum pressure rating is 58.02 PSI (400 kPa), which is 3.5× the full-scale range; this burst pressure margin protects against overpressure events in pneumatic lines or altitude excursions during shipping.
