Hi Doug, 2nd version was almost done as a prototype 2 years ago, but because of a other projects, we did not finished the full firmware tests. There a a lot of features and a lot of various operation modes combinations, which equired a lot of time to test.

BTW, I got many questions this year bout it.
(Why this year? Why not 0.5y/1y or 1.5y ago? I don't know! Covid influence? ).
So maybe I will force it now.

Alex I'd purchase one as soon as they are available. I'd love a remote (USB or ethernet) interface too...

I'll drop you a message.

Ethernet is too complicated, USB exists (USB2COM, isolated).

Can somebody tell from their own experience how much current is the ES9038PRO taking from:

+1.2V Analog (VDD_L, VDD_R)
+3.3V Analog Reference (AVCC_L, AVCC_R)
+1.2V Digital Core (DVDD)
+3.3V Digital I/O (AVDD)
+3.3V Oscillator (VCCA)

I am confused by the numbers in the data sheet (attached).

- Are these per channel (L/R) or the sum of currents on both channels?
- Why are VDD_L, VDD_R and DVDD collapsed under the same value, are they assuming one will use the 1.2V supply to feed both the Analog and Digital Core sections.

I read that the current value scale up (as expected) with the clock frequency, @100MHz and 768KHz is almost double the values @40MHz and 48KHz, anybody has any current consumption measurements @100MHz?

ES9038PRO eval board appears to power DVDD, VDD_L, VDD_R all from the same regulator.
