I only need one, but tbh I'm not sure if there's a particular "version" I need or what. Battery Name: Sanyo 18650 cylindrical lithium-ion batteries Battery Type: UR18650NSX Battery Specifications: 18 * 65 (MM) Battery material: Lithium-ion (Li-ion Lithium Ion Battery) Battery Voltage: 3.6...

And Yes my stock of parts is well out of hand

Think I've 4 new Sanyo cells here how many u need?

Have some here

I can't see how having two Rs (one on each output) to GND changes anything. Though his output voltage might be measured differentially between the two, that wouldn't change the offset, which would be zero measured between the two output pins. ahhh.. its because there mono, outputs are in parallel d...

looks great, loads of room maybe we can turn the dac board 90 degrees so the i2s input is facing the sd card player, and maybe we can mount the usb to i2s converter above the dac board somehow and have a usb extender cable to the rear panel? in favor of keeping the i2s cables as short as possible

Ok I don't know why but dc offset is 2.7v and output is much higher than 300mv with the 135r in. Afair was same with dddac

well its 135r between + output and gnd and anther 135r between - output and gnd
maybe thats the confusion?

that would make the filter u did wrong aswell?

Dc offsets are circa +/- 2.75v on the differential outputs at 133ohm iv Think it's either 800 to 1000mv output ac I went over to the DS to confirm - its putting out 6.2mA at BPZ, the total swing is 7.8mA. So I'd expect 800mV DC on those 135Rs and the swing is between 300mV and 1.3V so 370mV RMS. It...

Coz all the regulators are in series we opted for plastic backed regs to save worrying about shorts on the heatsink https://uk.farnell.com/stmicroelectronics/ld1085p/v-reg-adj-1-25-28v-1085-to220fp3/dp/1087151 These super caps are an absolute pig to charge up. 360 farads Maybe 20 min( have not time...
