Hello

I have some question about AD5412

 

As i see in the datasheet i can connect "Io" and "Vo". just need a buffer .

your recommended buffer is  Dual Op-amp .

I don't need bipolar output range (-5~+5 ,-10~+10) because i don't have dual power supply on my board.

So i have to use single supply op-amp .

As you know most of the single supply opamp that have low offset are very expensive .

Could i use an ordinary (not low or ultra  offset) like lm358 as buffer ?(i have tested in zero input out put is about 13 mv).



Could i Connect "io" to "Vo" even when i use Boost ?
