On the schematic is says:
Buffer Input = 700 mV = 3.09375 V * R / (1000 + R)
This gives R as 292, rounded to 300 ohm. This is wrong. It should be:
Buffer Input = 700 mV = 3.09375 V * R / (2000 + R)
This gives R as 585 ohm, rounded down to 576 ohm.
On Rev 1.0 and Rev 1.1 you need to replace R510 R610 and R710 with a 585 ohm resistor (or slightly lower is fine)
This mistake means the maximum output voltage is actually ~0.4V and so the picture is a bit dim.

Sorry, something went wrong.
Replaced DAC component to fix #177

560R is the best JLCPCB have.
