The current batch o 24 bit R2R DAC hat is completed finally. I just finished assembling a few of them , and since there are a lot of demand out there, I will keep making this DAC, and for those who are interested and PM me previously, I will reply your PM for detail. This V2.4 DAC has individual switch for each bit, and lower internal resistance. it can accept up to 24 bit 384K , and output stage is discrete non-feedback buffer, with 1.75V output, and around 600++ohm of output impedance. Sorry for the low quality camera at low light :
