ADM3065EBRMZ-RL7 Übersicht
RS-485 is a robust differential serial communication standard widely used in industrial environments due to its long-distance capability (up to 1200 m) and immunity to noise. The ADM3065E family integrates a driver and receiver in a single package, simplifying PCB layout and reducing component count. As a transceiver, it converts TTL/CMOS logic levels to differential bus signals and vice versa, enabling reliable data exchange between multiple nodes on a shared bus.
Key features include ±12 kV IEC ESD protection on the A and B bus pins, which safeguards the device against electrostatic discharge events common in industrial settings. The transceiver also features a wide common-mode input range, ensuring reliable operation in the presence of ground potential differences. The 50 Mbps data rate supports high-throughput communication, while the half-duplex configuration allows bidirectional data flow over a single twisted-pair cable.
The ADM3065E uses a standard RS-485 architecture with a differential driver and receiver, providing robust signal integrity over long cable runs. The device includes thermal shutdown and short-circuit protection, enhancing system reliability. Its low quiescent current and wide supply range make it suitable for power-sensitive applications, while the MSOP package offers excellent thermal performance for its size.
Typical applications include industrial control systems, building automation, HVAC controllers, and motor drives. The high ESD rating and wide operating temperature range make it ideal for harsh environments. When designing with this device, ensure proper termination resistors (typically 120 Ω) at both ends of the bus to minimize reflections and maintain signal integrity.
For optimal performance, place the transceiver close to the bus connector and use a solid ground plane. The device is available in tape and reel packaging (RL7 suffix) for automated assembly, facilitating high-volume production.

Wichtigste Unterscheidungsmerkmale
- Higher data rate (50 Mbps) compared to many alternatives (vs. MAX3485EESA+T)
- Superior ESD protection (±12 kV IEC) (vs. SN65HVD72DR)
- Wider supply voltage range (3.0 V to 5.5 V) (vs. MAX3485EESA+T)
Designhinweise
Place the ADM3065EBRMZ-RL7 close to the bus connector to minimize trace length and reduce EMI. Use a solid ground plane beneath the device and route the A and B lines as a differential pair with controlled impedance (typically 120 Ω). Add 120 Ω termination resistors at both ends of the bus to prevent signal reflections. Keep the RE and DE pins properly biased to avoid unintended bus contention.
Decouple the VCC pin with a 0.1 µF ceramic capacitor placed as close as possible to the pin, and a 10 µF bulk capacitor nearby. The ADM3065EBRMZ-RL7 operates from 3.0 V to 5.5 V, so ensure the supply is stable and within this range. For noisy industrial supplies, consider adding a ferrite bead in series with VCC to filter high-frequency noise.
Do not exceed the absolute maximum ratings, especially the bus pin voltage relative to GND. The ±12 kV ESD protection is for IEC 61000-4-2, but it does not protect against continuous overvoltage. Ensure proper grounding and avoid ground loops. When using the device in half-duplex mode, ensure only one driver is active at a time to prevent bus contention. Use the RE and DE pins to control direction.
