TLV320AIC3104-Q1: independent register configuration of two devices using same I2C Bus

Part Number: TLV320AIC3104-Q1
Other Parts Discussed in Thread: TLV320AIC3106

Hello All,

In which way would it be possible to configure two tlv320aic3104-q1 connected to the same I2C Bus independently?

The datasheet does mention any information about adapating the I2C address.

Section 9.5.2 in the datasheet

"The TLV320AIC3104-Q1 responds to the I2C address of 001 1000."

Best Regards

Joern

    Joern,

    The Address for the AIC3104 is fixed. If you want to use multiple devices, you can either multiplex the I2C bus for those devices, or even use different I2C ports on the process if that is possible.

    The TLV320AIC3106 is the parent device to the AIC3104 and it can have the address set to one of 4 choices. So a third option would be to use that device, or a combination of the AIC3104 and aic3106.

    best regards,
