ISO5125I-65 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the ISO5125I-65?
  The maximum operating temperature range for the ISO5125I-65 is -40°C to 125°C.
• How do I ensure the ISO5125I-65 is properly biased for optimal performance?
  To ensure proper biasing, connect the VCC pin to a 5V to 15V power supply, and the EN pin to a logic-level signal (e.g., 3.3V or 5V) to enable the device.
• What is the recommended PCB layout for the ISO5125I-65 to minimize EMI and noise?
  To minimize EMI and noise, use a multi-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a common-mode choke or ferrite bead on the output.
• Can I use the ISO5125I-65 in a high-reliability or safety-critical application?
  Yes, the ISO5125I-65 is designed for high-reliability and safety-critical applications, such as industrial, medical, and aerospace systems, and meets relevant industry standards (e.g., IEC 60601-1, DO-160).
• How do I troubleshoot common issues with the ISO5125I-65, such as output voltage droop or oscillations?
  To troubleshoot issues, check the input voltage, output load, and PCB layout; ensure proper decoupling and filtering; and verify the device is properly biased and enabled.
