DAC8871EVM: DAC8871EVM

Part Number: DAC8871EVM

Hello,

I have a problem, I don't have voltage on output. Do you see a problem in my schematic in attachment.

I drive th chip with arduino. See code below :

IOWrite(GPIOA, CS_DAC3);
delay(10);
SPI.transfer(0x4f); // config0
SPI.transfer(0x4f); // config0
IOWrite(GPIOA, CS_OFF);
delay(10);

Do you have an idea?

Thank you 

Best Regards
