The ADM485JN is an integrated chip combining an RS-485 transceiver and an RS-422/RS-485 transceiver (also known as 4-wire buses). It is designed to be used in an industry-standard, multipoint RS-485/RS-422 system. This chip is ideal for transmitting and receiving digital data over long distances. It has superior EMI protection, circuit protection, and a low power consumption.

The ADM485JN belongs to the interface - drivers, receivers, and transceivers family. It is used to transmit and receive digital data over long distances. It has a robust design to handle EMI (electromagnetic interference) and is capable of operating in a wide range of temperatures. It has a successful track record in many industrial applications and is the ideal solution for transmitting and receiving digital data over long distances.

The ADM485JN works on the principle of two-wire EIA-485 (also referred to as RS-485) communication. It features high-speed data transmission, up to 256 computers or nodes can be connected in one network, and it also supports half duplex transmission. The EIA-485/RS-485 protocol uses differential signaling in which the swings of the signal on the two wires are in opposite phases. When the voltage difference between the two wires is zero, the corresponding bit is considered as null or logical 0; otherwise the bit is considered as one or logical 1. Thus the ADM485JN uses a differential receiver and transmitter to encode and decode the digital data.

The ADM485JN is compatible with various applications such as industrial automation and control, multi-point communications, AT/PC/Ethernet boards, as well as other forms of digital data transmissions. It is also used in video surveillance systems, such as closed-circuit television systems, as well as other signaling equipment. It supports data rates up to 28 Mbps and distances up to 1 km.

The ADM485JN is available in a convenient JEDEC SOIC (Small-Outline Integrated Circuit) package and it is designed to with stand high electrical and magnetic fields, which is ideal for industrial applications. It also features automatic baud rate detection and adjustable receiver sensitivity. The power consumption is also very low; it requires 5 volt supply and few 10 mA of current. It is also easy to setup and configure and meets the requirements of EIA/TIA-485-A and IEEE/ANSI standards.

In conclusion, the ADM485JN chip is an ideal solution for transmitting and receiving digital data over long distances. It is not only compatible with various industrial applications, but also with EIA/TIA-485-A and IEEE/ANSI standards. It is easy to setup, requires a low power consumption, and offers superior EMI protection and circuit protection.
