NovaSensor NPA Series of Surface-Mount Pressure Sensors features a high stability SenStable® piezoresistive MEMS chip placed in a SOIC 14-pin miniature thermoplastic package, and is intended for printed circuit board mounting. The sensor module contains a pressure sensor die and a signal-conditioning ASIC that eliminates the need for an additional IC from the customer. The NPA Series is available in single and dual port configurations with either mV, amplified analog, or digital outputs. The sensor monitors pressure in industrial and medical applications by producting a voltage output that is linearly proportional to the input presure.
