I need to design a quad-channel ADC plus USB interface. The application is four-channel audio recording. Normal voice frequency range should be fine.
Does TI have any suitable ADC and USB interface chips?
Please accept my apologies for the slow response to your question. Texas Instruments does not have any stand alone analog to digital converters with a direct USB interface that I am aware of. There are OMAP, Stellaris and MSP430 processors that have native USB though which might be suitable for voice band audio. Please have a look over the product portfolio here:
In reply to Tom Hendrick:
I have similar requirement like David. I need to connect 4 or 8 analog audio channels to OMAP-L138 EVM. Can you suggest some thing.
