NPA-300B-015D
Overview
The NPA-300B-015D is a surface-mountable pressure sensor that provides a calibrated, temperature-compensated analog output for measuring differential pressure up to 15 PSI. It utilizes NovaSensor's MEMS silicon-on-insulator technology to achieve high stability and sensitivity in a compact 14-SOIC package. This sensor is designed for board-level integration in systems requiring precise gas or liquid pressure monitoring without the need for external signal conditioning components.
Why Choose This Part
The sensor features an on-chip ASIC that provides a pre-amplified analog voltage output (2V to 3V), significantly reducing the complexity of the host PCB. It offers a wide operating temperature range from -40C to 125C with an accuracy rating of +/-1.5 percent, ensuring reliability in harsh industrial or automotive environments. Its dual-port barbed configuration allows for easy and secure attachment of standard 3mm (0.12 inch) tubing.
Applications
Key Specifications
Getting Started
To evaluate this sensor, provide a stable supply voltage between 3.135V and 3.465V to the VDD pin and ground the VSS pin. The analog output can be directly interfaced with a microcontroller's ADC; ensure the ADC reference voltage is compatible with the 2V to 3V output swing. Use the dual barbed ports to connect tubing from the high-pressure and low-pressure sides of your system to measure the differential value.
