I am currently working with the EVAL-AD5761RSDZ. I am trying to control the DAC with a Python script running on a Raspberry Pi.
As far as I know I have to write to the control register after powering up. By sending 0x04 04 11 the DAC should be configured to the output range from 0V to 10V. Then I can use the write and update command, 0x03 ff ff, to set the voltage output to its maximum. However, the output remains unchanged at 0V. I have also tried to start with a "software full reset" command, but the result is the same. While checking the connections of the DAC I couldn't find any issues. The signal on the MOSI line goes into the chip, as well as the CLK signal, the sync signal and the provided power.
Do you have any idea what I could be doing wrong or how I can solve this problem?
