Hi,
I'm new to TI's line of DSP products and was hoping I could find some advice here. I'm prototyping a low latency device for a biological application. The device needs to input two analog voltage channels via an ADC, do some processing that involves using the input voltage as the input variable to a simple equation, and then output the value as a voltage via a DAC channel. Each pair would be independent, i.e. AI1 is the input used for AO1, and AI2 is used for A02. The application needs 16-bit resolution on the ADCs and DACs at 20kHz per channel. It would be nice to have a +/- 10V input range, but I can condition the input to be smaller, say +/- 1V or +/- 2V. The specifications mentioned are the minimum requirements, so there would be nothing wrong with a higher sample rate or resolution, or more channels.
The TMS320C6713 DSP Starter Kit seems like a good place to start, however, it doesn't integrate the ADC and DAC component that the application requires. Next Dimension Technology's AD6M daughter card is almost what I would need, I think, but it's only 12-bit. From some of the other posts TI makes something called the 5-6K Interface Evaluation Module as well as a number of other ADC and DAC evaluation modules. I apologize for my ignorance about your product line: when using the evaluation modules (EVMs) do I need to purchase both the EVM and the appropriate ADC/DAC chip or is the chip included with the EVM? Can you provide some more information about the daughter card as well as a recommendation for ADC and DAC modules I would need to assemble a working prototype?
Thanks very much,
Nicholas
