ISO7021DR Frequently Asked Questions (FAQs)

  • 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.
  • Use a thermally conductive material for the PCB and ensure good airflow. Keep the device away from heat sources and avoid thermal gradients. Use a heat sink if necessary, and ensure the device is properly soldered to the PCB.
  • Use a pi-filter (C-R-C) or a T-filter (L-C-R) configuration with a common-mode choke and a capacitor to filter out high-frequency noise. The filter values depend on the specific application and frequency range.
  • Use a shielded enclosure, keep the device away from the enclosure walls, and use a low-pass filter on the output. Ensure good PCB layout practices, such as minimizing loop areas and using a solid ground plane.
  • Power up the device in the following sequence: VCC, then VISO, and finally the input voltage. Ensure a monotonic power-up sequence to prevent latch-up or damage to the device.
