PCM1808: Finding products that can use the ECHO (microphone) function

Part Number: PCM1808
Other Parts Discussed in Thread: TLV320ADC3101

HI

ADC is under review for new products.

Changing the karaoke microphone to a digital signal is the main function

Currently, ECHO IC is also being applied.

There seems to be a product that includes DSP among TI products.

Please check if the ECHO (microphone) function is applicable.

1. PCM1808 (Stereo ADC)

2. TLV320ADC3101 (Stereo ADC with miniDSP)

- Possibility of Echo function (specified by 3-D)

    Hi, Kim,

    Both devices you mention are ADCs, however, for a mic application, I would recommend the ADC3101. This device as an integrated PGA which is required to pre-amplify the mic signal amplitude. Also, the ADC3101 features a miniDSP which could be configured by user to create custom audio processing flows. Can you provide more details about the ECHO function you want to achieve in your application?.

    Best Regards,
