ADS1261: ADS1261BIRHBR vs ADS1261BQWRHMRQ1

Part Number: ADS1261

Hi,

I've looked and cannot find anything to decode the TI part number and would like to know the difference between:
ADS1261BQWRHMRQ1

and 

ADS1261BIRHBR

It is clear the device package is different but otherwise I'm not clear on what the other differences are. 

Thanks,

Tyler

    Hi Tyler,

    welcome to our e2e forum and thanks a lot for your interest in our ADS1261.

    I can help you decode the letters after the "ADS1261B".

    • First letter is the temperature range indication.
      "Q" stands for the automotive temperature range from -40°C to 125°C
      "I" stands for the industrial temperature range but can be -40°C to 85°C, 105°C or 125°C
    • The next few letters are the TI package designators.
      "RHB" for the 32-pin QFN package
      "WRHM" for the wettable flank 32-pin QFN package
    • Thereafter follows the carrier type.
      "R" in this case indicates a large tape&reel.
    • "Q1" indicates that this device is AEC-Q100 qualified for automotive applications

    The main difference between the two devices is that one device is the version qualified according to AEC-Q100 for automotive.
    Both devices have the same features and functionality. There might be slight differences in the MIN and MAX parameter specifications.

    Regards,
