The I2C address of an AIC is available in the data sheet. The I2C address is 7 bits wide, however, the transaction on the I2C bus consists of one byte and therefore, if the AIC address is given as a hexadecimal number, it is expanded to 8 bits. Most of TI's AICs released in 2007 and 2008 have an I2C address of 0011000. In our control software (GUI), this 7 bit number is expanded to 8 bits (by adding an extra LSB) and represented as 0x30.
If the AIC doesn't have a configurable I2C address, you must use an I2C splitter, if you want to connect multiple AICs to the same I2C bus in order to avoid address conflicts.
