ADS8558: Interleave to support up to 2Msps

David Huang

Part Number: ADS8558

Hi Team

I'm looking for a 12bits ADC solution with sampling rate higher than 2Msps.

The analog input voltage is 15V, and can be divided to 3V-5V via resistors.

Can ADS8558 support this with interleave? Do we have any other solutions to this in our portfolio?

Regards

    Hello, 

    The ADS8558 is only a 730kSPS sampling rate device. 

    Would you provide more detail as to what are some other requirements for the device? the ADS8558 is a multi channel simultaneous device, to find a multiple channel device that can reach 2MSPS will be rather difficult.  There is the ADS7863A ~click here~, that is a multichannel, simultaneous sampling device

    I suggest looking at the at the ADS7049-Q1 ~click here~ it is a 12 bit, 2MSPS single channel device, it is very small, thus multiple devices can be used in a small footprint. 

    I also did a quick parametric search, based on resolution, sampling rate, and SPI interface, and found 16 device ~click here~

    Regards
