Overview

The DLHR-L05D-E1BD-C-NAV8 is a high-resolution 18-bit digital pressure sensor designed for ultra-low differential pressure sensing within a +/-0.18 PSI range. Utilizing CoBeam2 technology, it provides high stability and sensitivity for demanding applications requiring 0.25% accuracy. It operates over a wide supply voltage range of 1.75V to 3.6V and features a temperature-compensated output accessible via I2C or SPI interfaces.

Why Choose This Part

This sensor offers exceptional 18-bit resolution which is critical for resolving very small pressure fluctuations in the +/-1.25 kPa range. Its low-power architecture consumes only 2.6mA during active conversion and features a 250uA sleep mode, making it suitable for battery-powered handheld instruments. The dual-port barbed DIP package simplifies pneumatic connections while providing a robust through-hole PCB mount.

Applications

Medical Respiratory Monitoring
Ideal for breath-by-breath analysis in ventilators and anesthesia machines due to its high resolution and low-pressure sensitivity.
HVAC Variable Air Volume (VAV)
Used for precise air flow control and filter pressure drop monitoring in energy-efficient building automation systems.
Industrial Leak Detection
Employed in sensitive pneumatic testing equipment to detect minute pressure changes in sealed systems.
Environmental Controls
Suitable for monitoring cleanroom pressure differentials and laboratory fume hood airflow safety.

Getting Started

To interface with the sensor, connect the SCL/SDA or MISO/MOSI pins to your microcontroller and provide a stable 1.8V or 3.3V supply. The device defaults to I2C address 0x29 but can also be accessed via SPI depending on pin strapping. Use the 18-bit digital output to read compensated pressure and temperature data without the need for external ADC or calibration circuitry.
