8 channel DAC need a 8 channel digital input.

Amanero are working on a new USB-I2S module with 8 channel so we can start some test with this in the future.

In any case this is another project completely different.

I have an exa21 usb to i2s converter that feeds 8 channels of i2s. Will this work with your board? Can your board be configured for 8 channel balanced output?

The chip can output 8 channels. I wonder if it is possible to configure this board to allow that....

Default The Opamp I/V on 6 ch BuffaloIII

Hi!

I wold like to use your OpAmp I/V amp for my 6 ch DAC (based on BuffaloIII from Twisted pear).

The output from this is;
4 ch with 4mA pp and
2 ch 8 mA.

What I/V resistor ? Is it OK with 40 ohm for the 4mA and 20 ohm for the 8mA? Can I adjust the gain from the OpAmp I/V stage if I want?

Best regards
