ADM2491EBRWZ Frequently Asked Questions (FAQ)

  • A good PCB layout for the ADM2491EBRWZ involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the isolation barrier. Additionally, using a shielded cable for the differential pair and keeping the cable length as short as possible can help minimize EMI.

  • To ensure proper isolation, use a separate power supply for the ADM2491EBRWZ, and make sure it is not referenced to the system power supply. Use a transformer or a DC-DC converter to isolate the power supply, and ensure that the isolation voltage rating is not exceeded.

  • The maximum cable length that can be used with the ADM2491EBRWZ depends on the specific application and the type of cable used. As a general rule, the cable length should be kept as short as possible to minimize signal attenuation and EMI. A good starting point is to use a cable length of up to 10 meters, but this can be extended to up to 100 meters or more with proper cable selection and signal conditioning.

  • To troubleshoot common issues with the ADM2491EBRWZ, start by checking the power supply and ensuring that it is within the recommended range. Check the input signals and ensure that they are within the specified range. Use an oscilloscope to check the output signals and ensure that they are correct. Check the PCB layout and ensure that it is correct, and check for any signs of physical damage or overheating.

  • When selecting a suitable isolation voltage for the ADM2491EBRWZ, consider the maximum voltage that can be present between the input and output circuits, including any transient voltages. Ensure that the isolation voltage rating is sufficient to withstand the maximum voltage, and consider factors such as the type of isolation barrier, the operating temperature range, and the desired level of safety and reliability.
