Look in www.cygnal.com.
They have very fast ADC. But is 12 bit. Mybe you can do beter res. with
interpolation. Look app. notes on web site.

Or try with Analog Devices audio AD converters. They are wery fast with
hi resolution.

16 bit ADC at 8 kHz

Hello,

From this descriptin I think this will be an audio applications. In this case I suggest ou to take audio codec which you can interface through SPI and have all audio filters built inside - otherwise you will need quite powerfull CPU to realize this filters.

In my application I use 16 bit TI DSP TMS320LF2407(a) (30(40) mips) and TLV320C1106 or you can use TLV320AC36 which costs app. 3USD. This audio codec can be interface on any platform which have SPI on minimum 2MHz - This is standard surce clock for most of Codecs.

Regards!

mcu + adc

I sincerely think you begin to consider to use separate device,in this way you will have a lot of chance in performance and costs.

The AK5371 is a low-power, stereo input ADC with a built in USB interface. This device is perfect for USB microphones, microphone arrays, and USB audio capture and headset applications. If a USB codec is required, check out AKM's AK4571.
