I'm using AD5755 DAC with clear code funcionality. It is configured for 0V. The module is correctly configured and signal CLEAR is okey.
When I have a voltage output, per example 5V at output, after I remove module from backplane, CLEAR goes high and output goes to 0V. The problem is when I did this test several times. In some cases, output doesn't go to 0V and remains at 5V. It is a intermittent problem. Some times I have to remove 10 times to one error, and other times more than 20/30 times. In error situation, pin CLEAR goes high as expected and SW can't be responsible as there isn't power at microcontroller, only in DAC.
So, is it an AD5755 internal problem ?
