AD5732  can't let VoutB output

Moved to more appropriate community

Hi, Cao.

When setting the power control register, A2, A1, and A0 should be set to 0. Could you be able to set A2 to 0 instead of 1?

Hi, Cao.

It would greatly help me understand your problem if you could provide a schematic diagram. Please include working supply, references, and logic levels. Would you also be able to answer some questions regarding your problem?

• Are you able to change the level on VoutA?
• Will you be able to double check your timing? You may check Table 3 for reference.

according to you guide, the VoutB can't output ..  the waveform as follow.    /load , /cs and /clear signals are appropriate.

Could you give me more help. thanks a lot.

answer：

1.  I can change the VoutA output Voltage Range(for example : +-10.8V  +-10V  +-5V);

2. SCLK's  period  is 200us. all the timing are approprate.

supply +-15V 

reference  +2.5V 

logic level +3.3V

AGND and DGND is connected.

Hi, Cao.

Everything looks good to me. I just have some questions. What is the difference between AVC_IN_O and DVC_IN_O?How are you measuring the output voltage on the part? Where is pin 5 of the part connected to?
