Can ADuM4190 be used to measure DC voltage signal?

Question

Hi, 
 Can ADuM4190 be used to measure DC voltage signal? 
 We need to design a voltage measure system, which frequency is from DC to 1KHz, as ADum4190 use iCouple technology, we want to know whether it can be used in this sytem as the isolated amplifer? 
 Thanks and best regards,

Hello HarWoo, 
 
 Yes, the ADuM4190 can be used to measure DC signals, as well as the 1 kHz signal that is well within the 200 kHz bandwidth of the part. The easiest way to achieve this is to connect COMP to -IN, and connect your incoming signal to the +IN pin. The ADuM4190 has an input common-mode range of 0.35 to 1.5 V, and you can use a voltage divider to condition the incoming signal to fit that linear band.
