to whom it may concern,
I'm trying to daisychain two DAC088S085, but I can't make Dout of the first one to output any signal, while I can control the analog outputs of the first DAC cprrectly, I'm not sure why the Dout won't respond. Right now, I'm using the TSSOP package. Couple of months ago I used the WQFN and at some point I was able to make Dout work, so I believe the code I'm using is correct. In the pictures below you can see the nSYNC (ch2), SCLK (ch3) and Din (ch4). As explained on the manual, I'm sending 32 falling edges of SCLK, with nSYNC pulled down throughout. The Din code is 11000110 01100000 11000110 01100000 which would be broadcast to all channels the value 0x66 which is 2V with Vref1, Vref2 at 5V. In this case I would expect Dout to be 00000000 00000010 11000110 01100000 since in the manual it says the 15th cycle is high, but nothing comes out. Any information could help as I'm running out of udeas
Note in the picture the amplitudes of all signals are halved because all the channels on the scope have 50ohm plugs.
