AD5262 daisy chain

Hi

Please show me how to use daisy chain of AD5262.

In data sheet, the discription is only AD5260 single digi-pot.

 

I think a procedure for writing is

1. U2(A0=0)

2. U2(A0=1)

3. U1(A0=0)

4. U1(A0=1)

 

Is this correct ?

 

Best regards,

wada

  • Hi

    I have read carefully the D/S again.

    and I understood that the limitation is only "U2-->U1" and this sequence have nothing to do with address(Bit :A0).

    Therefore, the correct sequence for daisy chain of Dual Ch x2  is simply...

      U2(A0 = 0 or 1) --> U1(A0 = 0 or 1) -->U2(A0 = 0 or 1) --> U1( A0 = 0 or 1)

    Is it correct ?

    I'm sorry for basic question.

    But, our customer need a certain answer from ADI.

    Please, confirm.

    Best regards,
