Hello,
We are using DAC3174 in our boards in which its input data is coming from the FPGA. I would like to test the DAC standalone to address the design or code issues related to the DAC. Here are the values I have set for the internal registers:
050000
0046ED
01FE0E
030008
0cFFFF
15007F
I followed the initialization steps that are being suggested in the manual. I will be thankful if you could provide some inputs about the below issues:
- for the IO test, should all 8 registers (12-19) be programmed?
- the voltages that I am measuring at outAp and outAn are 300mV, after executing the code for SPI interface, I see a jump, and then it drops slowly. I was wondering whether you could provide some feedback about the possible root causes of this issue?
- the voltage that the output of DAC jumps after executing the code is constant regardless of the data being programmed in 0c. In other words, for both 0cFFFF and 0c0001, the jump is ~500mV.
I will be thankful if you could provide some feedback.
Sincerely,
Nasim
