Hi team,

My customer use two I2C devices, DAC7571(0x4d), ads1113(0x48),

at first, the DAC7571 set voltage 4.5v, then we write ADS1113 make the DAC7571 output to be 0.8v, we check it and find the address of ADS1113 is the same as Dac7571 broadcast address, Do we have some methods to solve the problem?

Thanks.

Frank,

Why are you using the broadcast address instead of the address defined by the A0 pin? Would using the A0 pin-defined address be an option?

Hi Frank,

I do not believe there is any way to make the DAC7571 not respond to its broadcast address. You customer will need to change the ADS1113 to a different address using it's address pin.

Thanks!
Paul
