    Any high end DAC operating in voltage mode?

    Most high end DACs (eg. ES9038Pro-based) operate in current mode. The outputs of the DAC are held at virtual ground and the current flowing out of them is converted to a voltage using an I/V converter (eg. using OPA1612). This gives a lower distortion (according to ESS datasheet). But it also...

    DAC output amplitude stability

    A lot of effort has been put into using highly stable clocks for high-performance DACs. There are even several Rb clocks on the market specifically for this application. Of course, this is an overkill from pure audio perspective, but makes sense from an abstract perfection point of view. There...

    DAC performance at very low frequency (1-20 Hz)

    Hello, I just stumbled onto this message board and was really amazed by the depth of the analysis. My interest in DACs is actually for scientific experiments to generate very clean signals and it seems that audio DACs are well ahead of other test equipment in this frequency range. But I am...
