• AD7621: FAQs

    Q 

    We would like to use the AD7621 or AD7641 in our project.
    Does the AD7621 can work with SPI interface in 1.25, 2 and 3 MSPS?
    Does the AD7641 can work with 16 bit and SPI interface in 1.5 and 2 MSPS?

  • 关于AD7621 AD7622 AD7641

    在使用AD7621 AD7622 AD7641时存在一个同样的问题，即bit0到bit4（pin9、pin10、pin11、pin12和pin13）没有输出，只有bit5到bit15有输出。

    导致输出数据如图 低五位一直是0。有朋友遇到过同样的问题吗？求指教谢谢！
