ADuM4195-1 output offset voltage

Hi tchen340, thanks for your question.

What kind of application or configuration do you want to implement?

Could you please provide a short description in order to better address the question?

Thanks

Hi AAlessandro,

ADuM4195-1 is for constant current channel paraller application. diagram at below.

now, if Ch-1 is 0A. ADuM4195-1 inpuit have 0V. but because output offset is  ±5mV. 

so Ch-2 will tiny current output. 

ADuM4195-1 how to eliminate (or reduce) the output offset voltage by using an external circuit?

thanks.

Hi tchen340,

the ADuM4195-1 is an isolated opamp with fixed gain (=1). For the isolated amplifiers there is no easy solution at System/PCB level that can be done to reduce the output offset.

Regards,
Alessandro

HI Alessandro,

thanks for your reply. do you konw ADI have there are low offset isolator amplifier product plan?
