ADS1610 + ???

Other Parts Discussed in Thread: ADS1610

Hello Everyone!

I had to make a 16-bit A/D converter that is acquiring data every 100ns for few seconds (over 10^7 samples). I decided to use ADS1610 but I am wondering how to store the data and further simply send it to the computer via the USB. TI suggests FIFO + TMS320 DSP processor. Is it the cheapest solution? What other possibilities would You consider taking into account that the price is an important factor?

Best regards, Jerry.

    Hi Jerry,

    There are potentially hundreds of solutions here - are you taking samples with the ADS1610 at 10MSPS for 'a few seconds' and then transferring all of that data back to the PC before taking another series of samples (say minutes or 'many seconds' later)?

    Hello Tom,

    thank You for Your reply. I see my problem this way:

    1. computer sends signal to the processor (microcontroler) to start measuring

    2. the analog signal is digitalized by ADC every 100ns ("real time") and stored in the memory

    3. after, e.g., 10^7 samples (or more), the ADC stops converting and saving data

    4. computer program requests data from the memory

    5. data are send by USB to the computer

    best regards, Jerry.
