ive ran 2 feet of wire between lifepo4 and devices before without any recognisable loss in sq which suits my funky testing methods :) Long leads are ok, as long as there is sufficient capacitance at the load. High speed analog and digital devices are more sensitive. any more thoughts on bypassin th...

nige2000, I am confused by your replacing the electrolytics with film caps. I would have thought you would not have wanted any capacitance at all? Rick, the opamps supplying the DAC will need a certain amount of capacitance in order to maintain dynamic performance. Without caps and with the long le...

would be difficult not to experiment with this dac i have many projects not finished myself im hopeful that this will be one of the best dacs ive heard to date with some modding/filters whats the plan for the 4 volt reference? Ah, sorry I didn't see this question until now. I just want to see exact...

Thanks for the welcome and the reply. The opamps I'm referring to are those buffering the 4V references, not the output parts. Looking at the board, I suspect they are the 5 pin parts on the other side of the resistor ladder to the 5V regulators. I don't have the DAC yet, I'm trying to discipline my...

Hi Nige,
what caps are you planning to use? I'm also curious what the reference buffer opamps are ... can you tell? Also, can you see how the reference filtering is being done? Would definitely want a film cap there rather than ceramic.
