ADM2487E - High Speed, Isolated RS-485 Transceiver with Integrated Transformer Driver

ADM2482E - High Speed, Isolated RS-485 Transceiver with Integrated Transformer Driver

При передаче данных на большой скорости и на большое расстояние применяется дифференциальная технология передачи данных. Дифференциальная передача позволяет свести к минимуму влияние неодинаковости потенциалов "земли" и влияние помех, которые являются синфазным сигналом. Спецификации RS-485 описывают требования для многоузловой сети, в которой возможно наличие 32 драйверов и 32 приёмников на одной двухпроводной линии. Некоторые приемопередатчики RS-485 могут изменять входной импеданс, что позволяет подключить к одной линии в 8 раз больше узлов. Наиболее типичное применение сети RS-485 - это программируемые логические контроллеры в условиях промышленного окружения. Другие примеры применения - объединение кассовых терминалов в крупном магазине или удаленные измерительные блоки. Analog Devices предлагает большой выбор приёмопередатчиков RS-485 для разнообразных систем.
