Compact ADP910 digital differential pressure sensor for −500 to +500 Pa with an I²C interface. The source record states ±3% of reading accuracy, <2 ms response time and operation with non-condensing air, nitrogen or oxygen. Confirm the exact transfer function, port configuration, calibration and application approvals before integration.
Description
ADP910 Digital Differential Pressure Sensor with I²C

Typical applications include HVAC airflow control, filter monitoring, gas appliances, laboratory equipment and embedded differential-pressure measurement. Medical, oxygen, combustion and safety-related applications require confirmation of the exact sensor variant and all applicable approvals.
Use the required 0.1 µF external supply decoupling and follow the manufacturer's port orientation, pressure limits and I²C timing requirements. Confirm the digital transfer function, I²C address, sampling mode, overpressure rating, media compatibility, calibration and connector or PCB footprint before design-in.
