Housed in a 14-pin SOIC surface mount package, the NPA Series is available in gauge, absolute and differential pressure ranges with either mV, amplified analog or digital outputs. The sensor is intended for printed circuit board mounting and delivered in tape-and-reel for ease of manufacturing.

Features of Respiratory-Specific NPAs:
• Surface-mountable
• Differential, gauge, absolute and low pressure
• Up to 5 PSI full scale
•  Output Options: Amplified Analog, Digital Serial (14bit), Digital I2C, Uncalibrated mV
• On-chip temperature sensor in digital mode
• Operating temperature range of -40°C to 125°C
• Fast response
• High accuracy


Applications:
• Ventilators
• Oxygen Concentrators
• Sleep Apnea (CPAP)
• Medical Respirators
