Design Notes

For the ADM2487EBRWZ, maintain a minimum creepage distance of 8 mm between the logic side (pins 1-8) and bus side (pins 9-16) to meet the 2.5 kVrms isolation rating. Use a PCB with adequate clearance and avoid placing copper traces under the device. Place the external transformer close to the VISO and GNDISO pins to minimize parasitic inductance and ensure stable isolated power.

The ADM2487EBRWZ requires a 5V supply on both VDD1 and VDD2. The integrated transformer driver generates an isolated supply (VISO) using an external transformer and rectifier. Ensure the transformer has a suitable turns ratio (e.g., 1:1) and that the rectifier diodes and capacitors are rated for the required current. The typical quiescent current is 2.5 mA, but the bus side may draw more during transmission.

For RS-485 networks, terminate the bus with 120-ohm resistors at both ends to prevent reflections. Place the termination resistors close to the connector. Use twisted-pair cabling for the A and B lines. The ADM2487E's high CMTI (25 kV/µs) helps reject common-mode noise, but proper grounding and shielding are still recommended for long cable runs.
