AD8369 control bits lines

Question asked by on Mar 13, 2018

I am using AD8369 in my design. Please let me know when I keep DENB - HIGH, will the control lines (BIT0, BIT1, BIT2 and BIT3) be in tri-state or in a low impedance state.


Also I am planning to use 16 AD8369 in my board. I am planning to have common control bus across 16 devices with separate DENB/SENB line for each device. 

        - Can I do this?

        - If yes, do I need to add any buffer's for each device or I can just have a common trace routed to all devices?

        - If 16 is not possible what is the maximum number of devices I can control with a common control bus?
