This datasheet also covers the Si8941 variant, as both devices belong to the same isolated delta-sigma modulator family and are provided as variant models within a single manufacturer datasheet.
General Description
The Si8941/46/47 are galvanically isolated delta-sigma modulators which output a digital signal proportional to the voltage level at the input.
Key Features
Low voltage differential input - ±62.5 mV and ±250 mV options.
