LM5066: how to use I2C communication?

Part Number: LM5066

Hello TI experts,

my customer design the product with LM5066, and they want to use I2C communication.

In pin description I can see \SMBA, SDAO, SDAI, SCL.

but i should connect only 2 pins in I2C communication, SDA and SCL.

I think SCL is fine, but where should I connect for SDA? SDAI or SDAO?

and I have one more question, I will connect 9 LM5066s to one MCU in parallel.

is there something I should know for it? like pullup or pulldown resistor or something.

please check these issues. Thanks.

Best regards,

Chase
