I tied /LADC pin to GND, and /CLR pin to VDD on hardware connection.
I used an FPGA to sent config signals to AD5643.
First I sent 00_111_000_0000_0000_0000_0001 to use the internal reference, I can see a 2.5V output on the REFOUT pin.
Then I sent 00_011_111_1111_1111_1111_1111 to config DAC output ,but I can't see output on the VOUTA and VOUTB pins, they are still 0V.
How should I do to get the right output? Should config more registers?
