Why has the TPS65070 the same I²C Address like the broadcast address of all TI DACs????

Its 1001000 and thats not really funny... if you put the LED PWM and all DAC reset!!!!

    I apologize for any inconvience this may have caused.  Given the limited number of available BITs, there is always the possibility of address overlap between two ICs.  Hopefully you can reselect different components with different I2C addresses and still meet your electrical requirements.

    ___EVERY___  DAC from TI has the broadcast adress 1001000

    How can TI use this adress for any other Chip? Does TI engeneers speak to TI engeneers?

    Is this true no OMAP L138 with its companion chip TPS65070 ever can be used with any DAC from TI?

    In the datasheed of the TPS65070 there is mentioned the availability of some other I2C Adresses? What does this mean for small quantities e.g. 1k pieces?
