Hi Team,

I am choosing a Power AMP for customer but found that TI has no such solution.

Customer requirement is I2S digital Input, Two channel output 2*1W, only need 3.3V or 5V power supply..  

I also go through our product in ti.com.

Nearly all the I2S digital need at least two power supply...And if having two channel output, the output power is also very large...

Do we have such a solution? If no Power AMP can meet there requirement, I think DAC(I2S input)+Power AMP also ok..

    Hi Amelie,

    For such low power, some DACs can fit but as you mention they need more than 1 supply.
    Regarding DAC+Power amp, the supply requirements would still be the same...

    Some options are:

    • TLV320DAC3100
    • TLV320DAC3120
    • TAS2505
