Part Number: TLV320ADC5140

Hi,

Does TLV320ADC5140 is the same with CS48LV41F are Far-field voice processor?

Also for microphone array? And is it integrated algorithm?

My customer's project need support digital microphone array, two microphone.

Thanks!

Hi Jeff,

the ADC5140 is suitable as a far field voice processor. There is a video here that discussed the DRE and PGA that make it suitable for this application. https://training.ti.com/far-field-voice-capture-adc

And the TLV320ADC5140 can support up to 8 digital microphones. I am not certain the customers exact needs, but I would expect this could meet them.

Regards,

Arthur

Hi Arthur,

My customer need support 2~4 microphone array and need AEC/NC/Far field beamforming algorithm support.

Do you know TLV320ADC5140 also integrate above algorithm? or they need own the algorithm by themself?

Thanks!

Hi jeff,

I am not certain if those algorithms exist in this device. I will look into this and post back in a couple days.

Hi Jeff,

The customer will need to implement these algorithms themselves.

ADC5140 will only perform ADC functions with high DNR - this does make the ADC5140 suitable for far field recording, but the algorithms will need to be implemented separately.

Arthur
