Подробнее о продукте

AD5700 представляет собой однокристальное решение для реализации полудуплескного модема с частотной манипуляцией (FSK), соответствующего требованиям физического уровня интерфейса HART®. Микросхема содержит в себе все необходимые функции формирования, обнаружения, модуляции, демодуляции и фильтрации сигналов, и поэтому требует лишь небольшого числа внешних компонентов. Низкий потребляемый ток (115 мкА, максимум) и малый габариты посадочного места (4 мм × 4 мм) делают AD5700 оптимальным выбором для малопотребляющих схем с питанием от контура связи. Сигналы передаются синусоидами с частотой 1200 Гц и 2200 Гц без разрывов фазы. AD5700 содержит точную схему обнаружения несущей и использует стандартный интерфейс UART.

Области применения

  • Полевые передатчики
  • HART-мультиплексоры
  • Модули PLC и DCS с аналоговыми портами ввода/вывода
  • Системы, работающие по протоколу HART

Product Details

Both the AD5700 and the AD5700-1 products can be evaluated using the EVAL-AD5700-1EBZ Evaluation board. If evaluating the AD5700 product, simply disable the internal oscillator (i.e. configure the part to use either a CMOS clock or a crystal oscillator). No SDP board is required for this Evaluation board.
