Overview

The 4525DO-DS5AI001DP is a high-performance, 14-bit digital pressure sensor designed for low-pressure differential measurements up to 1 PSI. It features a dual-barbed side port configuration and provides a calibrated I2C output for seamless integration with modern microcontrollers. This sensor is temperature compensated and provides accurate readings within a 0.25 percent range.

Why Choose This Part

This sensor offers high resolution via a 14-bit ADC and integrates internal temperature compensation for stable readings across a -25C to +105C range. Its low power consumption, including a sleep current of only 0.6 uA, makes it ideal for battery-operated remote monitoring equipment.

Applications

HVAC Airflow Monitoring
Measuring pressure drops across filters to detect blockages and maintain air quality.
Medical Ventilators
Precise monitoring of differential air pressure for patient respiratory assistance.
Pitot Tube Airspeed Sensing
Calculating airspeed in drones and small UAVs by measuring differential dynamic pressure.
Pneumatic Control Systems
Low-pressure feedback loops in industrial automation and environmental control systems.

Getting Started

Connect the sensor to an I2C bus with pull-up resistors on the SDA and SCL lines using its 0x28H address. The 8-DIP through-hole package is breadboard-compatible for prototyping, and the 5V supply requirement makes it directly compatible with many standard development boards. Use standard I2C libraries to read the two bytes of pressure data and two bytes of temperature data.
