  • RE: TLV320AIC3204: PGA input referred noise

    Hi Marjin, Unfortunately the specific test points of 0, 10, 20, etc are not available. However you can extrapolate from the plot the referred noise. Best regards, Jeff McPherson

  • RE: TLV320AIC3204: TLV320AIC3204 I2C starts transmitting data with a "pa" sound

    Hi Luo, The AGC is present in the ADC signal chain, so the realized effect is through changes in the PGA gain.. If the INx inputs all have the same input signal level and the AGC gains up the signal to a defined value, each input will have the same result…

  • TLV320AIC3204: TLV320AIC3204 :How can the compression curves of HP channel and LO channel output ambient stereo be consistent?

    Part Number: TLV320AIC3204 Tool/software: Hello, I used LO and HP channels of 3204 for ambient stereo, set the same AGC and DRC parameters, and LO and HP hardware circuit parameters are the same, but the compression curves of LO and HP output ambient…
