How Next-Generation Isolated Sigma-Delta Modulators Improve Your System-Level Current Measurement
In this paper, we first introduce the common-mode transient immunity (CMTI) specification and its importance in a system. We will discuss a new isolated sigma-delta modulator family, its performance, and how it improves and facilitates system current measurement accuracy, especially for offset error and offset error drift. Finally, a recommended circuit solution will be introduced.
