Hi Team,

I saw that 3104 have one IO level. May I ask if my I2C is 3.3V but my I2S is 1.8V, in this situation, I need to add one level shift chip, such as TXS0104?

Thanks!

    Hello Amelie,

    That is correct... You have the correct understanding in that IOVDD for the TLV320AIC3104 sets the digital logic level for the device and will need a level translator. Digital logic level is used for  RESET, DIN, DOUT, I2C, and CLKs.
