DAC43608: Read back DAC register not working

Part Number: DAC43608

Hello,

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

Guenter

  • 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:

    Best,
