- Abstract
- This article describes a new class of multidifferential operational amplifiers used in instrumental amplifiers. These amplifiers are widely used in modern information and measurement technology, instrumentation, sensor systems, various analog-to-digital interfaces. A scheme of a multidifferential operational amplifier based on the KR140UD1A has been developed by adding an additional differential stage. Comparative studies of the frequency properties of the operational amplifier KR140UD1A and the multidifferential operational amplifier have been carried out. Conclusions are drawn about the influence of additional differential cascades on the frequency characteristics of the amplifier.
