ADC evaluation module like ADS1118EVM but with >5KSPS?

ADS1118EVM looks like a good evaluation module that can be hooked easily to our dev board through SPI interface. However, ADS1118 only supports 860SPS, while we need to supports at least 5kSPS with 16bit precision. Is there a similar ADC evaluation module supporting 16bit, SPI and higher sample rate?

Thanks,

    Penghe,

    Just about all of our data-converter evaluation modules fit to the same form-factor. Do you have any further requirements for the ADC to help focus on fewer devices?

    Kevin,

    I looked at quite a few suitable ADC chips (16bit, 0~5V, >5KSPS, SPI interface). They either don't have an evaluation module availabe, such as ADS1100, or the related evaluation module needs a separate board to interface with the main dev board, such as ADS8320. So could you just point me to one ADC that meets our requirements and also has an simple-to-use evaluation module ? Thanks.

    Penghe,

    Sorry I wasn't particularly clear in my response. Just about all of our EVMs fit to the same form-factor, but that is not the form factor of the ADS1118EVM. That guy is a little bit of a stand-alone one-off project we experimented with. We were able to support it in this instance because of the particular usage case of the evaluation module and the relative low speeds of that evaluation experience.

    The rest of our devices fit the the modular form factor EVMs that dock the the MMB0 you mentioned. The kits come fully assembled, motherboard and daughter-card plugged in and ready to go out of the box, and provide you with an in-depth evaluation experience with the paired ADCPro software that allows you to look at histogram analysis, FFTs, time-domain analysis, and view raw codes. The daughter card is fully function by itself - it does not need the motherboard to be used as evaluation hardware.
