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 provided in tape and reel form for simplified manufacturing handling. 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. An on-chip temperature sensor is included in digital modes, and the sensors feature a wide operating temperature range and a low Total Error Band.
