The ADM483EAR is an integrated circuit (IC) component designed by Analog Devices. It is a low-power, half-duplex RS-485/RS-422 transceiver with advanced features suitable for industrial communication systems.
The ADM483EAR offers a variety of key features that make it an ideal choice for data transmission applications. Firstly, it operates with a wide supply voltage range of 4.75V to 5.25V, making it highly compatible with standard industrial power supplies.
This IC component supports both RS-485 and RS-422 standards, providing flexibility for various communication protocols. It offers a high level of robustness through its enhanced ESD (electrostatic discharge) protection, preventing damage from static discharges up to ±15kV.
Another noteworthy feature is its low-power consumption, making it suitable for battery-powered or low-energy applications. The ADM483EAR also features a low-level input voltage, which allows it to operate with weak drivers or lines in noisy environments.
Additionally, this IC component can handle data rates up to 250kbits per second, making it compatible with high-speed communication requirements. It supports half-duplex operation, allowing for bidirectional data transmission on a single pair of wires.
The ADM483EAR includes a fail-safe receiver input, which guarantees a high level on the receiver output in the absence of a valid input signal. The receiver also implements a differential receiver threshold to improve noise immunity
