NPB 102 Barometric Pressure Sensor

Amphenol Advanced Sensors’ NPB 102 is an absolute pressure sensor with digital output for low power consumption and applications with a wide operating temperature range. 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.
