The ADM483EARZ is a high-performance, half-duplex RS-485/RS-422 transceiver designed by Analog Devices Inc. It operates on a single 5 V supply and features a maximum data rate of 250 kbps. The device is housed in an 8-pin SOIC package, making it suitable for a variety of industrial and communication applications. It is designed to comply with the TIA/EIA standards for RS-485 and RS-422, allowing up to 32 transceivers on a single bus.
Transceiver ADM483EARZ Features
The ADM483EARZ offers several key features that enhance its performance and reliability. It includes ±15 kV ESD protection, which ensures robustness against electrostatic discharge in harsh environments. The transceiver also features a reduced slew rate to minimize electromagnetic interference (EMI), making it suitable for sensitive applications. Additionally, it has a wide common-mode range of -7 V to +12 V and a low supply current of 36 μA, with a shutdown mode that reduces current to 0.1 μA. The receiver is designed with a fail-safe feature, guaranteeing a logic high output if the input is open-circuit.
ADM483EARZ Applications
The ADM483EARZ is ideal for applications requiring stable data exchange and robust signal integrity over long distances. It is commonly used in low-power RS-485 systems, electrically harsh environments, and EMI-sensitive applications. Other typical applications include DTE-DCE interfaces, packet switching, local area networks, industrial automation control, and fault-tolerant network designs. Its ability to support up to 32 nodes on a bus makes it suitable for extensive network coverage.
ADM483EARZ Advantages
Choosing the ADM483EARZ offers several advantages. Its ±15 kV ESD protection ensures high reliability in environments prone to electrostatic discharge. The reduced slew rate minimizes EMI, making it ideal for applications where signal integrity is critical. Additionally, its low power consumption and shutdown mode help conserve energy, making it suitable for battery-powered or energy-efficient systems. The wide common-mode range and fail-safe receiver design further enhance its robustness and reliability.
