Can I use multiple ADG729's with same I2C address?

Hi All,

I was wondering if it was OK to use multiple ADG729's (ie ~3 or 4) in a design that all have the same I2C address.

I want them to change (near) simultaneously, so I was thinking that may be an option. Does anyone have any experience with doing that?

Kind Regards,


  • Hi Matt,

    I have no experience with using multiple ADG729 with the same I2C address but it something that is definitely not recommended when using the I2C protocol. With multiple devices replying with an acknowledgement, there is no way to guarantee the correct operation of the I2C communication. Having them operating with different 12C addresses would definitely be my recommendation.
