is it possbile to read out Registers from several daisy chained AD5410's, becuase readback operation in daisy chain mode is not described in the data sheet?
Do you already multiple AD5410s setup in daisy chain?
If yes, you could try the following sequence to perform a read on a specific DAC in the chain.
For example you have 3 DACs configured and are already able to do the write sequence in daisy chain and you want to read the 2nd DAC in the chain.
1. send 1 no-op (3rd DAC); readback command (2nd DAC); 1 no-op for the first DAC (total of 72 clock cycles; then Latch high
2. send 3 no-op commands + Latch High
The readback of the 2nd DAC will be on the 2nd 24-bits from the output the 3rd DAC.
thank you for you suggestion, it sounds very feasabile. At the moment I am doing hardware evaluation, the prototype will not be finished until summer.
When I have results I'will post it here.
after receiving a Prototype, the described Method of daisy chain register readback works properly
