1. Describe

The ADM2582EBRWZ is a fully integrated signal and Power Isolated Data Transceiver with ±15 kV ESD Protection Suitable for multi-point high-speed communication Transmission line. The ADM2582E/ADM2587E include a Integrated isolated DC-DC power supply eliminates the need for An external DC-DC isolation block is required. They are designed for balanced transmission lines, conforming to Complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). These devices integrate Analog Devices, Inc.'s iCoupler® technology Combined with a 3-channel isolator, a three-state differential line driver, The differential input receiver and Analog Devices isoPower® dc-todc converter are integrated in one package. The device is powered by a Single 5 V or 3.3 V supply for fully integrated signal and Power isolated RS-485 solution. The ADM2582E/ADM2587E drivers have an active high enable. also provides an active low receiver enable, which results in The receiver output goes into a high impedance state when disabled. The device features current limit and thermal shutdown Features to protect against output short circuits and conditions Bus contention can cause excessive power consumption. These parts are fully specified over the industrial temperature range range and are available in a highly integrated, 20 lead, wide body SOIC package.
