Low cost ES9018 DAC board GB

[syllable]

I will put low value on the customs declaration. Please be patient. I will despatch all orders in 10 to 12 days or much earlier.

Is it possible to have the ES9018K2M's datasheet please. I will use a personal software so I need it.

Thks.

 

[dady]

Master Syllable, do the same treatment with my shipping value. Please of course.
Best Regards

 

[dady]

I received a email with the BOM, the layout and the circuit. This correspond to the boards you going to ship me?
Best Regards

 

[Ryssen]

Thanks for the zipfile.
What is the current draw of the 3,3v and AC9v and 15-0-15v lines?

 

[linuxguru]

Thanks for the schematic, BoM and silkscreens. I was able to locate most of the datasheets, except the full datasheet of the ES9018K2M (which is probably available only under NDA).

Could you also send pdfs of the top and bottom layer tracks? I found what appears to be an error in the schematic on the left side of IC1, the ISO7230 I2S isolator, and the i2s connector. I'd like to see what's the best way to bypass or workaround that possible issue.

 

[syllable]

There is no error, already tested the board, probably you didn't clearly understood the schematic, you can work around once you have the board in hand. Just keep waiting for a while.

INA and INC (pins 3 and 5) of IC1 ISO7230 are shown as shorted together on the schematic sent. I'm reasonably confident that that was not the intent, and that each of INA, INB and INC goes to 3 different signal pins on the i2s input connector.

Did you test the board with the i2s isolator installed, and i2s input to the isolator?

 

[syllable]

Not really, the connection line from 3 just passes over 5 but there is no physical connection between these two. I will mail you the snapshot of the tracks of that section. Check it out.

Let me know where you found the shot between 3 and 5

 

[linuxguru]

Cool, looks fine on the layout.

Hi syllable

If you can't provide the complete datasheet, please provide the register setting description at least.

Thanks!

It will be helpful for anyone who wants to control DAC chip via I2C via external device. I plan to use the DAC board with an arm and the arm will control the dac chip via I2C.

...and in a worst case, the difference between the ES9018 and K2M version!

 

[syklab]

I plan to use the arduino nano V3.0 ATMEGA328P to control the DAC but need to figure out how to work the display.

[Ryssen]

What is the reason of using the microcontroller,is it just to be able to switch between the 3 spdif inputs or are there other features?

Switch between three inputs, configure the GPIO pins to receive spdif signals, change the filters, change volume level. Without MCU it works at its default setting.

Hi Syllable,
Is it possible to set up for only one spdif signal using default setting? What is minimum circuitry required? Thank you. Regards.
