wireless microphone 2.4G Receive/transmit 

The ADC i used PCM1803A，recently i find the group delay of PCM1803A is too high，my boss give me another choice：AK5720

Does TI have another better group delay ADC？

    Hi Gary,

    Yes, TI is currently previewing The TLV320ADC3140 which is a 4 channel Audio ADC.

    There are 3 modes for the decimation filters.
    here are the delay times for 48/44.1khz mode:

    Standard mode: 17.1/Fs Seconds
    Low latency mode: 7.7/Fs Seconds
    Ultra low latency mode: 4.1/Fs Seconds


    Best regards,
