How I can use two chips TAS5518C on one I2C bus?

It will work correctly if I make so:

SCL pass through "OR" element and second input of this element used as negative chip select

Constantine,

As far as I know, it does not, but I can't guarantee this as we've never played around with this.

Usually, we just recommend customers use an I2C expander IC to allow multiple parts on the same bus. This is the only 100% guaranteed safe method.
