The TAS576xM has 7 bits for its own slave address. The first five bits (MSBs) of the slave address are factory preset to 10011 (0x9x). The next two bits of the address byte are the device select bits which can be user defined by the ADR1 and ADR0 pins. A maximum of four TAS576xMs can be connected on the same bus at one time. This gives a range of 0x98, 0x9A, 0x9C and 0x9E. Each TAS576xM responds when it receives its own slave address.
