Hi everyone, 

I'm trying to program the AD5504 chip by using external SPI master controller. (Arduino uno, SPI level 5V)

which configuration for the jumpers LKx?

LK1 has to be removed.

VDD have to be provided from external DC power supply? i think so.

Vlogic? has to be provided from external DC power supply? LK9 has to be set to C configuration or can remain at 5V (A configuration).

something else? LK2 and LK3?

thanks
