ADM4850ACPZ-REEL7 Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADM4850ACPZ-REEL7 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces connected to the RS-485 bus pins. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure EMC with the ADM4850ACPZ-REEL7, use a shielded cable for the RS-485 bus, keep the cable length as short as possible, and use a common-mode choke or ferrite bead to filter out electromagnetic interference (EMI).
  • The maximum cable length supported by the ADM4850ACPZ-REEL7 depends on the baud rate and the type of cable used. As a general rule, the maximum cable length is 1200 meters at 9600 bps and 300 meters at 115200 bps.
  • Termination resistors are required at both ends of the RS-485 bus to prevent signal reflections. A 120-ohm resistor is recommended for each end of the bus, and the resistors should be placed as close to the ADM4850ACPZ-REEL7 as possible.
  • The recommended power-up sequence for the ADM4850ACPZ-REEL7 is to apply VCC first, followed by VDD. This ensures that the internal voltage regulators are powered up correctly.
