How to make simple I/V from full Diffential out DAC

Van Hai · 24th December 2005, 06:30 AM

Since i have two DAC, AK 4316 and AK4382 i would like to make a use for its, no opamp, the output from the DAC L+ L-, R+ R-. Can any one to make it unbalance?

regards,

Can someone help me? maybe no opamp to unbalance out.

Any one?

Six transistors or three 6SN7's plus a few passives should do it. Do you have the datasheets?

Are these voltage output DACs or current output DACs? I can't find any datasheet for them. Just a bunch of Chinese websites that list every part number known to man to try and lure you to their site. I tried a few of them but none had any datasheets available.

Anyway, a transformer would be a very simple, high quality way to do what you want to do. However without the datasheet I can't recommend the best way to do it.

This should work, assuming they are voltage out devices. Its only a basic outline and obviously needs more work.

i think it is voltage output DAC, what is good about full differnential out put dac, is there any good for unbalance, hope someone can help. please have a look at the data sheet.

Thanks rfbrw i will try to work out your schematic, can i use BC550 and BC560.
