Which are the TI's ADC with the most number of simultaneous Channels? I´m currently using the ADS131E08SPAGR but I need to duplicate the channels. Is it possible?  In case it was no possible. How can I synchronize both ADCs?

    Hello,

    In our recent releases, 8 channels is the highest number of simultaneous sampling ADC cores.  Some examples are listed below for both 8 and 4-channel simultaneous sampling options.  Devices like the ADS131M08 have a "Sync" pin function that can be used to synchronize the sampling acquisition timing of multiple devices. 

    8-Channels:
    ADS131M08
    ADS8588H
    ADS8588S
    ADS1278

    4-Channels:
    ADS131B04-Q1
    ADS131M04
    ADS131A04
    ADS8584S
    ADS1274
