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 available in gauge, absolute, and differential pressure ranges with various output options, including amplified analog, digital serial (14-bit), digital I2C, and uncalibrated mV. They feature an on-chip temperature sensor in digital mode and are delivered in tape and reel form for simplified manufacturing handling. The NPA Series is suitable for a wide operating temperature range and provides a total error band of less than 1.5% FSO.
