Усилители с малым входным током смещения (< 100 пA)

ОУ с малым входным током смещения требуются в ситуациях, когда разница токов или напряжений мала и должна быть измерена с малой погрешностью. Входные каскады таких ОУ не нагружают источник сигнала. Применение ОУ с малым входным током смещения крайне важно для задач интерфейса с датчиками, такими как фотодиоды, датчиками pH и другими датчиками типа электрометров. Компанией Analog Devices выпускается множество прецизионных ОУ, которые способны удовлетворить требованиям таких приложений.
