DAC43608: Read back DAC register not working

Part Number: DAC43608


we are using the DAC43608 in our application. Everything works fine except for read back of the DAC values.
Read back of configuration and status register is working. When I try to read the registers 8-15 I always get
0x0000 as results no matter what was written before.

Writing definitively works. The DAC outputs are changing according the written values.

What I am doing wrong?

A SW reset is done before using the DAC. LDAC input is not used and set permanently to low.

Thanks and regards


  • Hi Guenter,

    These registers are labeled as W only:

    That is probably why they are reading back as 0x0000. Registers that can be written to and read from have R/W in the Type column of the register map like the PDN bits in the device_confg register:
