As of now there are several versions of this board so this thread is becoming a little confusing. Anyhow, I just received version 2013.07 of this board along with the DIYINHK XMOS 384kHz USB to I2S PCB. Everything looks great but there are markings and connections on the board which could use some documentation. For a newb like me this would really make things much less intimidating. Unfortunately, no documentation was included so I hope some good soul could perhaps make a list of these markings and explain their function.

I also have a few specific questions that hopefully someone will answer.

1. I would like to use the clocks from the USB to I2S pcb, so I don't plan on installing an oscillator on the DAC board. Do I need to connect anything else besides the I2S inputs between these two boards? Will the ESS chip recognize automatically that it needs to derive its timing from the I2S signal? Or maybe I have to connect something to between the X1 connection of the DAC and the USB board?

2. Can anyone else verify that going with separate left/right AVCC supplies is as good as DIYINHK claims?

3. If going with separate supplies for AVCC should these also have separate dedicated transformer windings or can they share the same one?

4. I plan on using this DAC with a single ended SRPP tube buffer, any hints as to where exactly I should steal the signal points on the board? Obviously I won't be populating the opamps and rest of the IV stage. Will the chip automatically operate in voltage mode if I connect these outputs to a 50k pot through a coupling cap? What if I want to use current mode, how do I enable it and what size of resistor do I use before the buffer?

5. What is the marking "Chip Address" on the DAC board used for?

Thanks in advance for the replies.

I2S connection are right, sabre board is already running ,volume remotecontrol
with digelaty dsp.
sound high dynamic, friends are very impressed.

thank all

1 - You can use the master clock output from the XMOS to the clock input of the ES9018.
3 - Same transformer would be fine.
4 - Dac operates in voltage mode without an I/V even if you put a resistor across the output. For true current mode you need to fix the output voltage with an opamp.
5- Chip address is to set the address of the chip if you are using dual mono.

please can somebody tell me what is a tp level converter .
how is the shematik or can i by it.
i am building also the diyinhk sabre dac,and i need spdif input into the sabre dac, an wich pin is the input and gnd.
i have the last pcb diyinhk made 2013.05.

TP level converter: The Buffalo III Digital-to-Analog Converter

It is to convert the consumer spdif levels (~1v) to 3.3v required by the DAC.

For the DAC, the default input for spdif is data-1

Has anyone experienced excessive heat on the ICs, particularly in the buffer? I have been strangely loosing LME49990's within just few weeks.

My ES9018 is about 30-40 degrees, and my opamps(ADA797) is maybe 40-50 degrees.
All other cirsuits is on modified boards like Musiland and so on.

I meant IV opamps, 6 LME49990s. I've build two boards, both have the same heat problem. What may cause that?

Worst are the last two opamps, they reach ~90-100 degrees Celcius. I have changed power supplies, built multi-stage regulated supply with independent Salas LV regulators for analog, digital, and IV stages, noisewise they are very clean and voltages are not exceeding the standards; 3.3V for digital, 3.45V for analog, and 12.2V for IV. I'm seriously puzzled.

Maybe they are oscillating, proper decoupling as recommended in their data sheet is very important for proper operation.
