Product Overview
The NPA Series of Surface-Mount Pressure Sensors offers a cost-effective solution for applications requiring calibrated performance in a miniature size. These sensors are designed for printed circuit board mounting and are delivered in tape and reel form for simplified manufacturing handling. Available in gauge, absolute, and differential pressure ranges, the NPA Series provides various output options including uncalibrated mV, amplified analog, and digital serial (14-bit) or I2C outputs. An on-chip temperature sensor is included in digital modes. The sensors are suitable for a wide operating temperature range of -40C to 125C with a total error band of less than 1.5% FSO.
