Transformers for Analog Devices ADM2485

Murata Power Solutions has announced a series of transformers that simplify implementation of isolated RS-485 and RS-422 interfaces based on Analog Devices chipsets by eliminating the need to select, compare and test alternative solutions.


    Transformers recommended by Analog Devices for use with ADM2485 transceiver
    Low profile device offers 2.5kVrms isolation and industrial temperature operation
    Accurately controlled turns ratio for consistent performance
    Toroidal construction maximises efficiency and reduces EMI

 Each device in the 782485 converter transformer series has been specifically designed for use with the Analog Devices ADM2485 high speed, isolated differential bus RS-485 transceiver. Fully approved by Analog Devices, the transformers are also recommended in the company’s ADM2485 datasheets and reference design documentation. The transformers are supplied in a low profile (6.35mm), fully encapsulated package with an industry standard DIL pinout. Surface mount versions will be available soon. Incorporating an internal transformer driver, the Analog Devices ADM2485 is deployed in isolated RS-485 and RS-422 interfaces as well as Profibus networks, industrial field networks and multipoint data transmission systems. Combining the device with a Murata Power Solutions 782485 transformer, an LDO regulator and a small number of discrete components allows designers to implement a fully isolated 5V power supply.
