Regarding AD5761 DAC

Hi.
I've connected the AD5761
For the programming of the AD5761, I did the following steps:
- write to control_reg <= X"0400DE";// output range =0 to 15V
I load the input dac register with X"ffffff" data to get 15V on Vout
The Vout is always 0V, the signals seem to me correct.

what is the problem

  • Hi,

    After you write to the control register, can you please use the readback control register command to check whether the control register values matches to what you actually wrote?

    What are the levels of your supplies (DVcc, Vdd, Vss)? and what are the levels of your logic signals (SDO, SCLK,/SYNC)?

    Cheers,

    Ivan
