ADM3061EBRMZ-RL7 - 500kbps RS-485 Transceiver | Analog Devices
MPN： ADM3061EBRMZ-RL7 ✓ 啟用中ADM3061EBRMZ-RL7 概覽
RS-485 is a standard for multipoint communication systems, allowing multiple devices to share a two-wire bus. The ADM3061E is a transceiver that converts UART signals to differential RS-485 levels, enabling long-distance, noise-immune data transfer. It is part of the interface IC family, specifically designed for industrial automation, building control, and instrumentation.
Key features include a 1/1 driver/receiver configuration, half-duplex operation, and a receiver hysteresis of 30 mV for noise immunity. The device supports a wide operating temperature range of -40°C to +125°C, making it suitable for industrial environments. The MSOP-8 package offers a compact footprint, and the tape-and-reel packaging (RL7) facilitates automated assembly.
The ADM3061E uses a standard RS-485 architecture with a differential driver and receiver. The driver outputs are short-circuit protected, and the receiver has a fail-safe feature that ensures a high output when the bus is open, shorted, or idle. The device also features thermal shutdown protection to prevent damage from excessive power dissipation.
Typical applications include industrial control systems, building automation, HVAC controllers, and remote sensor networks. The wide supply range and ESD protection make it ideal for factory floor installations where electrical noise and transient voltages are common.
When designing with this device, ensure proper termination resistors (120 Ω) at both ends of the bus to minimize reflections. The A and B pins should be biased to a known state to avoid undefined receiver outputs when the bus is idle.

主要差異化特點
- Wide supply voltage range (3.0 V to 5.5 V) (對比MAX3485E)
- Extended temperature range (-40°C to +125°C) (對比ISL3170E)
- ±12 kV IEC ESD protection (對比MAX3485E)
設計說明
Place the ADM3061EBRMZ-RL7 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 device. For noisy industrial environments, add a 10 µF electrolytic capacitor in parallel. Ensure the ground plane is solid and continuous to provide a low-impedance return path.
Do not leave the RE and DE pins floating; tie them to appropriate logic levels to avoid unintended operation. When the bus is idle, ensure proper biasing to maintain a defined receiver output. Avoid exceeding the absolute maximum ratings on the A and B pins, as this can damage the device despite ESD protection.
