NPP-301A-200A
Overview
The NPP-301A-200A is a surface-mount absolute pressure sensor designed for reliable measurements up to 30 PSI. It utilizes a four-element Wheatstone bridge configuration and silicon piezoresistive technology to provide a 60 mV full-scale output from a 3V supply. Housed in a standard 8-SOIC package, it is optimized for high-volume automated assembly in cost-sensitive applications.
Why Choose This Part
This sensor offers high precision with +/-0.2% accuracy and solid-state reliability across a wide temperature range of -40C to 125C. Its 8-SOIC package enables easy integration into standard PCB assembly workflows without specialized mounting hardware. The Wheatstone bridge output provides a predictable linear response that is easily conditioned by standard instrumentation amplifiers.
Applications
Key Specifications
Getting Started
To use this sensor, connect the 3V to 10V supply to the bridge excitation pins and interface the differential output to a high-impedance ADC or an instrumentation amplifier like the AD8226. Ensure the PCB layout accounts for the non-ported nature of the device, as it measures ambient pressure reaching the die via the package. Calibration is recommended at two points to account for offset and span variations inherent in piezoresistive bridges.
