Isolated delta-sigma modulator based AC/DC voltage and current measurement module reference design

This isolated shunt based current measurement unit enables high accuracy current measurement without the use of Current Transformers (CT). The isolation is achieved through the use of AMC1304 that incorporates both high voltage isolation as well as the Delta-Sigma Modulator. This solution eliminates (...)
