• AD5259 I2C Device Address

    I would like to ask you about the I2C device address of AD5259. According to
    the documentation the complete address is changing by pins AD1 and AD0. In case
    of other components of the AD525x series the address is 0x58. Does the address
  • AD5259 communication problem

    Hi Engineering Zone,

  • AD5259 Power down

    Hi

    AD5259 power up sequence is

    GND, Vdd, Vlogic ,digital inputs and then VA,VB,VW.

    Power down sequence should reverse this, I think.

    Does AD5259 accept Vdd=VA=VB=VW=0V and Vlogic=5V ?

    Abso max accepts this, so it should be ok, I think.

    Could I make…

  • AD5259 i2c device adress

    Hello

    we want to use the AD5259 in a design.

    In the doc is no device adress noted.

    If i read the doc in the right way, there is a change over the

    whole adress by setting ad0 pin. Normally there is a change of only 1bit.

    On this device the change…
