TMP441: The I2C signal setting

Part Number: TMP441

Dear team,

I found that the TMP441 can support both I2C and SMBus interface.

However, when I read the datasheet of TMP441, I found there were two input voltage settings for SMbus interface and digital inputs.

The screenshot of the datasheet is shown as below:

If I want to use I2C as interface, which input voltage should I follow? The 'SMBus interface' or 'digital inputs'?

I/m looking forward to your reply!

Thanks a lot for your support!

Best regards,

Xinyuan Li
