Pressure range and output resolution
The Infineon KP264XTMA1 is a digital barometric absolute pressure sensor covering 5.8 to 16.68 PSI (40 to 115 kPa) — the full atmospheric pressure band from high-altitude flight to sea-level weather stations. Its 10-bit SPI output gives 1024 counts across that span, so each LSB represents roughly 0.073 kPa (0.0106 PSI) of resolution.
Accuracy and temperature compensation
Total accuracy is ±0.435 PSI (±3 kPa) across the operating range — this is the combined error from offset, span, linearity, and temperature drift. The SPI interface and SMD (SMT) Tab termination keep the digital readout clean and the ground path low-inductance for the 8-SMD Module package.
Package and mounting for board integration
Housed in an 8-SMD Module with no port — the pressure inlet is the package top surface, so the sensor must be exposed to the ambient atmosphere via a vent hole in the enclosure. Surface-mount assembly with SMD (SMT) Tab termination; the tape-and-reel packaging (also available as cut tape) supports standard pick-and-place flow.
