A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for decoupling and place it close to the device.
Calibrate the device regularly, use a high-quality sensor, and ensure proper sensor placement. Minimize noise and interference by using a shielded cable and keeping the device away from high-frequency sources.
The maximum cable length for the I2C interface is 3 meters (10 feet). However, this can be extended up to 10 meters (33 feet) using I2C bus extenders or repeaters.
Yes, the ADPD144RI can operate with a 3.3V power supply. However, ensure that the power supply is clean and regulated to minimize noise and ensure accurate measurements.
Check the power supply, clock, and data lines for noise and interference. Verify that the device is properly configured and calibrated. Use a logic analyzer or oscilloscope to debug the I2C interface.
