• AD7621: FAQs

    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?

     

    The AD7621 can only use the full 3MSPS with…

  • AD7621 problem with serial interface

    We are using AD7621 which is configured to use as serial interface. FIN1031 deriver is connected to translate SCLK and SDOUT LVTTL signal level to LVDS level for SPARTAN6 FPGA and FIN1032 receiver translates CNVST LVTTL signal level from SPARTAN6 FPGA…

  • 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!
