Product Description
Product Overview
The NPA Low Pressure Series is a cost-effective, miniature surface-mountable pressure sensor designed for applications requiring calibrated performance. Available in Gauge or Differential pressure ranges, it offers amplified analog or digital serial (14-bit) / I2C outputs. The sensor features an on-chip temperature sensor in digital mode and a wide operating temperature range of -40 to 125C. Packaged in a SOIC14 pin surface mount, it is intended for printed circuit board mounting and delivered in tape and reel form for simplified manufacturing handling.
