Hello, ADI expert,
It is regarding to AD5412 design, the application uses as unipolar voltage output with +15V/0V/0V (AVDD/GND/AVSS) supply voltage.
When customer checked the AD5412 internal REFOUT is 4.900V that was below min specification.
I would like to have your advice what kind the possibility caused the Vref out of range.
Here is checked list:
1. Vout works well, but only could achieve 9.8V or 19.8mA output.
2. Whole GND pin soldering checked. (the EPAD can't confirm)
3. Analog power on first then Digital power.
