Patrick and Jan, thank you both so much for contributing! This IV converter certainly looks to be very, very exciting! Can't wait to sign up for the evaluation kit

Let's give it 2 weeks, so that the magazine could get to some of you who has already subscribed.

Really interesting stuff patrick - can't wait to read more about it in the mag.

I noticed on the measurements that the noise floor looks slightly higher on the CEN compared to SEN - is that component specific or a typology based difference?

I asked this question on the Zen I/V thread too: is the linearity of this circuit at least as good as that of a high end 24 bits DAC ?
If it isn't then the linearity of the system DAC+converter will be limited by the weakest link, i.e. the converter.

Good point. (I assume that you mean the I/V converter would be the weakest link, not the Digital-to-Analog Converter - there are two converters!)

If you look at linearity, I think you'll find that the power amp and loudspeakers are the weakest links.

That's what I meant.

Ok, but let's assume that I want to use a high performance DAC for something else than feeding a power amp, let's say I want to use it to build a high performance signal generator.
In this case I don't want my I/V converter to degrade the linearity of the DAC.
Is the circuit presented here good enough for this purpose ?
