ADM3065EBRMZ - 50Mbps RS-485 Transceiver | Analog Devices
MPN: ADM3065EBRMZ ✓ NakahandaADM3065EBRMZ Ulas
An RS-485 transceiver is an integrated circuit that implements the physical layer of the RS-485 standard, enabling differential data transmission over long distances (up to 1200 meters) and supporting multi-drop networks with up to 32 unit loads. The ADM3065E family is part of the broader interface IC category, which includes RS-232, RS-422, and RS-485 transceivers, and is essential for reliable communication in noisy industrial environments.
Key features include ±12 kV IEC ESD protection on the A and B bus pins (contact and air gap discharge), a wide supply voltage range, and a high data rate of 50 Mbps. The device also features a half-duplex configuration with a driver and receiver enable pin, allowing efficient bus control. The wide operating temperature range of -40°C to +125°C ensures reliable performance in harsh industrial settings.
The ADM3065E uses a differential signaling architecture that provides high noise immunity and common-mode rejection, essential for long cable runs. The transceiver includes thermal shutdown and short-circuit protection, enhancing system reliability. The 8-lead MSOP package has a thermal resistance of approximately 206°C/W (junction-to-ambient), which should be considered for high-temperature applications.
Typical applications include industrial automation, building automation (HVAC, lighting control), and instrumentation systems where high-speed, robust communication is required. The device is also suitable for motor control drives and remote sensor networks.
When designing with the ADM3065EBRMZ, ensure proper termination resistors (120 Ω) at both ends of the bus to minimize reflections. The enable pins should be controlled to avoid bus contention, and the A and B pins should be biased to a known state when the bus is idle.

Talaan ng Disenyo
Place the ADM3065EBRMZ close to the bus connector to minimize trace length and reduce EMI. Use 120 Ω termination resistors at both ends of the RS-485 bus to prevent signal reflections. Keep the A and B traces parallel and close together to maintain differential impedance.
Decouple the VCC pin with a 0.1 µF ceramic capacitor placed as close as possible to the pin. For noisy industrial environments, add a 10 µF bulk capacitor. Ensure the power supply can handle the transient currents during data transmission.
Avoid bus contention by ensuring only one driver is enabled at a time. Use the RE and DE pins to control the bus direction. When the bus is idle, bias the A and B lines to a known state using pull-up and pull-down resistors to prevent undefined receiver output.
