The ADM3485ARZ is an integrated circuit used as an isolation transceiver for isolation communication between two nodes. It is a configurable, low power, low latency, digital isolator with integrated dual-port memory leak protection.

The ADM3485ARZ is part of the Analog Devices\' Power by Linear™ Automotive Isolation technology family, which provides the highest levels of optical performance in automotive applications. The transceiver provides an 8-bit configurable digital isolator, with integrated dual-port memory leak protection and EMI/EMC noise filtering, as well as a range of additional features to help optimize the performance.

The ADM3485ARZ is designed for automotive applications such as ECU communication, fuel cells, electrical power steering systems, powertrain control, and instrumentation. It provides 8-bit configurable channels for open-collector, serial, and differential signals, and the integrated dual-port memory leak protection isolates the bus from any error during data transfer. The ADM3485ARZ also offers an integrated watchdog timer, adjustable slew rate limiting, and robust EMI/EMC filtering for protection against noise interference, so that it can be used in a wide variety of automotive applications.

The ADM3485ARZ\'s working principle is based on the concept of optocouplling, which is the process of isolating two circuits by the use of an optical element. The device includes a transmitter and a receiver, with each circuit induced by an optical link. The optical link utilizes the properties of light to achieve galvanic isolation. The physical processes that occur in optocoupling are the conversion of electrical energy into light and then into electrical energy again. The electrical energy is converted into light by a light-absorbing material (LED) which is connected to the transmitter and then the photons are converted back into electricity by a light-emitting material (phototransistor) which is connected to the receiver. The optical link between the two circuits allows for the isolation of the two circuits.

The ADM3485ARZ is a configurable device, enabling performance optimization with a variety of settings. It can be configured as 1- or 2-channel, vertical or horizontal components, and as a 3.3V/5.0V device. The device supports a wide range of input and output logic levels, with a maximum output rate of 5 Gbps. Additionally, the device has an adjustable slew rate limiting function, which can be enabled or disabled to optimize the performance. The integrated dual-port memory leak protection ensures that the communication between the two nodes is not affected by the errors or corruption in the data transfer. The device also includes a watchdog timer to detect a communication error in the circuit.

The ADM3485ARZ is a configurable, low power, low latency, digital isolator and is an excellent choice for a variety of automotive applications!.
