I want the isolation between input and output.But at the same time,looking for linear characteristics between input and output.
Can you pls confirm ,ADuM3190 device will work?.
The ADuM3190 is designed to work as an isolated error amplifier to provide isolated feedback in an isolated dc to dc converter, and will only give specified high accuracy of +/- 1% in this closed loop application.
For an application as an isolated amplifier with linear characteristics between the input and out, the ADuM3190 will be used in an open loop application, and the accuracy will be much less and determined by the output gain of +/-10% and output offset of +/- 0.4V, as specified in the output characteristics section of the datasheet. Also, you need to operate with the datasheet input voltage range of 0.3V to 1.5V.
Thanks for your reply.
For me accuracy is less priority.
For my requirement, the input voltage swing is 0-12V,So I need to convert this from 0.3V to 1.5V .
Pls confirm it.
The linearity error mentioned here is for unity gain or gain of 10
