TLV320ADC3001: TLV320ADC3001

Hi,

No MICBIAS is not required here and should be left disabled. You already have a bias provided by VCC_SW_3P3.

Please provide your configuration script and exact nominal clock frequencies. 1.5MHz will not work but 1.536MHz will.

Best regards,
Jeff McPherson

Hi ,

Hi Aman,

I see a lot of functions and definitions in this driver but it is not clear to me what configuration is actually written to the device? Maybe a register dump would be better.

Also please provide nominal clock frequencies.

Best regards,
Jeff McPherson

Hi Jeff, 

please find the register dump below after the configuration...

I am not sure about the meaning of the nominal clock frequencies required ...We tried driving the 24 Mhz clock to the codec from the ISP
