Усилители-датчики тока

Инструментальные усилители компании Analog Devices для токовых датчиков дают превосходные характеристики в разнообразных автомобильных системах и системах управления питанием. Эти усилители обеспечивают точное усиление слабых полезных напряжений на фоне высокого синфазного сигнала, обладают широкой полосой пропускания, а также обеспечивают сдвиг уровня и возможность измерения двунаправленных токов. Превосходная точность по постоянному и по переменному току в широком температурном диапазоне (от -40°C до 125°C) способствуют минимизации погрешности в измерительной системе без увеличения стоимости и габаритов корпуса.

Circuit from the lab Разработаны. Протестированы. Готовы к интеграции.
