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. Key features include an on-chip temperature sensor in digital mode, a wide operating temperature range of -40 to 125C, and a compact SOIC14 pin package delivered in tape and reel for simplified manufacturing handling. The sensor is intended for printed circuit board mounting.
