i/v conversion

Question asked by practys on May 4, 2018

Hello all,

Despite the ad1955 is not a modern converter, I believe the chip will still do his work.

I had still a few ic's on the shelf, so I decided to make a diy dac with the ad1955.

I have reading the datasheet a few times, the only thing what confuse me is this statement,

" Passive I/V conversion should not be used, since the dac performance will be seriously degraded." 

I like to know what this means, is an I/V output transformer not possible?

In my opinion opamps degraded the sound to, feedback and a bad power supply.

Is here somebody who can give an explanation about this topic?

Thanks a lot.
