Pressure sensor fits PCBA footprint for barometric applications

Digital compensation of the signal offset, sensitivity, and non-linearity is accomplished via a 26-bit internal digital signal processor (DSP) running a correction algorithm.

The calibration coefficients are stored on-chip in highly reliable, nonvolatile, multi-time programmable (MTP) memory.

The sensor is available in two standard pressure ranges with custom pressure ranges available upon request.

Packaged in a QFN configuration, the NPB 102 is intended for surface-mount printed circuit board assemblies. The package contains the pressure-sensing element and the necessary signal-conditioning electronics. The absolute pressure is measured through the port opening on top of the package (near pin 1).

This series provides a cost-effective solution that fits a standard PCBA footprint for barometric applications.

Pressure ranges are 260 mBar to 1,260 mBar and 50 kPa to 200 kPa. Operating temperature range is -40°C to +125°C.

The sensor is packaged in a 4 mm x 4 mm QFN allowing the AVI to detect the solder joint, It is AEC-Q100-qualified. I²C and SPI are available interfaces.

The devices enables ultra-low current consumption in sleep mode

Applications cover thermal runaways infotainment systems, indoor and outdoor navigation, consumer drones, weather forecast, altimeters and barometers for portable devices and enhanced GPS navigation.
