Product Overview
The NPA Series of Surface-Mount Pressure Sensors offers a cost-effective solution for applications requiring calibrated performance. These miniature sensors are designed for printed circuit board mounting and are delivered in tape and reel form for simplified manufacturing. Available in gauge, absolute, and differential pressure ranges, the NPA Series supports 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 suitable for operating temperatures from -40C to 125C, with a total error band of less than 1.5% FSO.
