I am working on Microphone arrays. So can anyone suggest me data acquisition modules or any products available for such applications?
It really depends on the bandwidth of your measurement, power and the dynamic range you require.
From the precision ADCs the AD7767, AD7767-1,AD7767-2 are devices which have been used for high dynamic range frequency analysis hook up to a microphone.
I'm guessing that you don't require any DC performance? is the system likely to be AC coupled?
What is your application?
Thanks for the response.
My applicatiion is speech signal acquisition using microphone arrays.
The kind of arrangement i am looking for is something like this::
microphone arrays connected to a data acquisition module. i would like the
daq module to have TDM or I2s interface to other modules.My bandwidth of
interest is of the audible range frequency(50-16 or 20 khz).
I am not coupling it to any ac circuits.
Do you have any product having

My apologies, I've only seen your response now - I didn't recieve an alert to your reply for some reason...
What dynamic range requirement do you have for the microphones? This really decides what products could be suitable.
Since we are using the mostky 16 bit sampling rate the dynamic range would be around 90 DB.
I am very much in need of the product. Waiting for ur reply.

Have you looked previously at AD7606:
This is an 8-channel simultaneous sampling ADC. It doesn't conform directly to I2S of direct TDM formats.
Take a look and see if this woudl suit your application?
