Digital isolators block high voltages that would otherwise be conducted on a two-line communication system, such as RS485, CAN, SPI, LIN, or Ethernet, with an isolation barrier of up to 150 kilovolts per second and electrical current up to 2.5 amperes. The ADUM225N0BRIZ-RL digital isolator is a member of Analog Devices’ Isolation Amplifier Family of products, which implements the company’s proprietary iCoupler® technology. This revolutionary technology uses micro-transformers, rather than optical components, to achieve galvanic isolation with superior DC and AC performance over standard fiber-coupled isolators. This provides a superior solution for superior communications and data exchange.
The ADUM225N0BRIZ-RL digital isolator provides high voltage galvanic isolation, i.e., blocking, for data lines up to 125VAC/DC for up to 150kV/s (IEC 61131-2). It offers excellent common-mode and normal-mode rejection ratio (CMRR/NMRR). It is available in 4-pin, 6-pin, and 8-pin packages. It provides guaranteed data rates of up to 250kb/s and a maximum signal frequency of 33kHz. It also features a low-power mode that reduces the supply current below 50uA.
The ADUM225N0BRIZ-RL digital isolator operates on a two-wire differential communication protocol, which allows for the isolation of data lines up to the full power range specified. This makes it suitable for a variety of applications, such as HVAC, building automation, factory automation, medical systems, and automotive control systems. It is also a popular solution for transmissions over long distances, since its high voltage blocking capability eliminates any need for a data conversion stage.
The working principle of the ADUM225N0BRIZ-RL digital isolator is based on the company’s proprietary iCoupler® technology. This technology utilizes monolithic integrated circuit technology and tiny transformers to ensure a high level of isolation between two circuits. These transformers are designed with two layers of electrodes on top of a dielectric material. When a signal is applied to one layer, the transformer allows the voltage or current to pass through the device, while preventing the signal on the other layer from interfering with the original signal.
The ADUM225N0BRIZ-RL digital isolator is a reliable and cost-effective solution for a variety of galvanic isolation applications. It has a wide voltage range and a high data rate, making it suitable for a variety of fields and applications. It is also capable of providing a high level of isolation between two circuits, ensuring reliable data transmission. With its advanced iCoupler® technology, the ADUM225N0BRIZ-RL digital isolator provides superior performance, reliability, and value must be the ideal choice for a wide range of applications.
