TLV320ADC3120: Would like to make the group delay longer

Shunsuke Yamamoto

Part Number: TLV320ADC3120

Hi team,

My customer would like to make the group delay longer. Are there any ways to do it without changing biquad filter parameters and digital dicimation filter parameters?

Best regards,

Try reducing the sampling Rate Group delay for decimation filters =k*(1/Fs). Lower frequencies for sampling should increase the froup delay.

Alternatively a hardware circuit can be made at the analog input of the ADC to create a group delay
