Use AD7399 DAC

Question

Hello! This DAC has inputs VREF. How to connect them to the supply power (Vdd)? Directly or through an external resistor? How to choose a resistor value depending on the desired voltage VREF?

Hi Vladimir, 
 You may connect them to VDD or have a resistor divider network to compute for your desired voltage on the VREF. Just make sure that your power supply can provide enough current for the other references.
