The ADM485JRZ-REEL7 is a differential transceiver for multipoint data-communication on balanced transmission lines.

The transceiver operates from a single supply that can range from +3V to +5.5V, and is designed to meet the RS-485 EIA Standards integrated circuit. It is intended for medium to low noise applications transmitting over balanced transmission lines and buses. This device is fully interoperable with the compatible SN55HVS14, MIT U10A, and INS82C15 types of transceivers.

Applications

ADM485JRZ-REEL7 primarily finds application as an interface between integrated circuit digital bus and multiconductor bus system. It features three-state output driving capability and transceives on a compatible line driver such as the SN75HVD12HH or the INS82C17. This device can also be used for balanced line control and for powering other circuits. Other applications include data communication, point-to-point short-haul multidrop, remote I/O control, and network communications.

Working Principle

The ADM485JRZ-REEL7 works by operating as either a transmitter or a receiver on a differential bus line. The data to be transmitted is input to the differential transmitter. This data is serialized in the differential transmitter and converted to differential signals. This is then output to the differential bus system. The data is then propagated through the bus system and converted back to logic level signals in the receiver by the differential receiver. The differential receiver input signals are then de-serialized and converted back to logic level signals. This data is then output to the receiver output resulting in the transmission of data without any errors.

The ADM485JRZ-REEL7 also features high-speed data transmission. The maximum data rate is 500kbps, ensuring a smooth and error-free data transmission. The wide common-mode input range, from -7V to +12V, allows data to be transmitted over longer distances.

The device also has a low operating current and power consumption, making it ideal for use in battery-powered equipment or applications requiring high reliability. The device also features low EMI (electromagnetic interference) and ESD (electrostatic discharge) protection, further increasing its robustness and reliability.

Conclusion

The ADM485JRZ-REEL7 is an ideal solution for medium- to low-noise applications requiring reliable and robust data transmission. Its wide common-mode input range and high-speed data rate make it ideal for data communication applications as well as for powering other devices. EMI and ESD protection make it suitable for use in a wide range of applications.
