ackoDAC based on ES9018

You missed the youngest member of the family, the 9016

Basically, it is only the ES9023 that won't go over 192k, which is plenty enough for me at this stage.

IMHO, there are better reasons to go for the 9012/18 or 9016 DACs over the 9023, their higher sample rate is nice but not the primary reason for going to the higher models.

Acko mentioned earlier that it was limited to 192, but then again the datasheet doesnt mention that the 9018 can either

That's odd. From memory the datasheet says max 500kHz input Fs for both the 9012/18 and the 9016.

Well I'm only going off the 9016 press pamphlet, I haven't read that datasheet.

I know, but its only specified a 192khz dac and no numbers are given for higher rates; it will as we know go much higher, however the clock speeds needed to do 500kHz with oversampling enabled are outside the recommended safe range

though I suppose 192x FS could be used instead of 256, but that doesnt really match their other specifications. its somewhat inconsistent that datasheet in this regard

Guys,

If you are talking about the 9016 DAC, the sampling frequency capability matches that of 9012/18, i.e. up to 500kHz

[qusp]

ahh, maybe you were talking about the 9023 when you mentioned the 192khz limit a couple pages ago. cool glad to hear that. what I was referring to was just that they dont specify performance at higher speeds than 192, even though it does say it can do it. if you do the math with the OSF on and take the max recommended XO speed at 256x fs you cant do 500khz, but you can if you do it at 192x fs, something to play with with the Si570 board

[acko]

Yes, you are right but within the current available standards of up to 384KHz audio then 256 x 384KHz = 98.304MHz MCLK

[qusp]

oh yeah 384 is no worries with the right clock, but not 500khz. its just not something they specifically outline, its possible the noise is slightly worse at the higher speed vs 192

Thanks, this was very helpful
