Product Summary
The ADM483EARZ is a robust, low power differential line transceiver suitable for communication on multipoint bus transmission lines. Internal protection against electrostatic discharge (ESD), electrical fast transient (EFT) and electromagnetic immunity (EMI) allows operation in electrically harsh environments. ESD protection on the I-O lines meets ±15 kV when tested using the Human Body Model. EFT protection meets ±2 kV in accordance with IEC1000-4-4, while EMI immunity is in excess of 10 V/m meeting IEC1000-4-3. Applications include Low Power RS-485 Systems, Electrically Harsh Environments, EMI Sensitive Applications, DTE-DCE Interface, Packet Switching and Local Area Networks.
