I can’t let the VoutB (AD5732) port output analoy voltage. Who can help me? Thanks a lot!
<1>setup both of DACs
<2>setup the A-channel and B-channel
<3> then setup the DAC register
Only VoutA output analoy voltage.@

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?
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.
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?
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.
logic level +3.3V
AGND and DGND is connected.
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?
