    Hi Hugo ,

    what do you mean by vendor or device ID ? According to the datasheet , the device has top side markings , or while buying from TI store, you will need to know the package you would need . I am unaware of device or Vendor ID .

    Hello Hugo Wang,

    Thanks for the question.

    When you ask for a vendor ID or a device ID, are you talking about if the device has an internal register with the device ID? The answer to this is no. The device does not have any internal device ID or vendor ID registers.

    If you are asking about a device marking, then yes. There are markings on the package, which can be see in the back of the datasheet, in the packaging addendum.

    In another note, I am moving this to the I2C forum, since this is an I2C device.
    Regards,
