6CH MIC input ADC （audio sampling），with echo eliminated function

Hello,

We are not going to have a 6-channel audio ADC solution with integrated Acoustic Echo Cancellation (AEC).  We have a new popular family of Audio ADCs, the PCM6260-Q1 which are meant specifically for microphone acquisition with diagnostics and integrated low-noise MICBIAS boost signal.  A combination of two TLV320ADC6140(4-ch) devices or a TLV320ADC6140 (4-ch)+TLV320ADC6120 (2-ch) would also work for 6 total channels with some higher performance options.

I mention them because even though they don't have any on-board DSP AEC processing they're very commonly used in 6-channel microphone systems with AEC and ANC type algorithms running on the host processor where more memory and MIPS are usually available for these acoustic algorithms.
