Technical Specifications

The SDP8490-303 measures differential pressure within a specified range, typically up to ±300 Pa. It operates on a low supply voltage, often around 3.3V. The digital I2C interface allows for direct communication with microcontrollers and other digital devices. The sensor incorporates internal calibration and temperature compensation to ensure accurate readings over its operating temperature range, which is commonly between -20°C and +85°C.

This pressure sensor is ideal for applications where high accuracy, small size, and low power consumption are critical requirements. Its digital output simplifies system design and reduces the need for external components.
