• Multiplexer for AD7641

    Hello!

    I'd like to use a MUX to extend the number of inputs for AD7641. I'm considering AD8180 and MAX393.

    Do you think adding one of these will reduce the effective ADC resolution?

    Are there other downsides? What should I look for when choosing…

  • AD7986 vs. AD7641

    Can anyone tell me what is the major difference between these two chips?

    BTW: Is the SMA (SMB?) adapter in the attached picture included in the EVAL-AD7986 package?  If not, where can I get it?

    Thanks,

    Shen

  • AD7641 Evaluation Board

    Hi,

    I am interested by AD7641, Is it possible to obtain gerber files of  evaluation board ?

  • 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！

  • AD7641 EVAL Board noise floor issues

    Dear all,

    I have set up the EVAL-AD76XXEDZ with the AD7641 and the EVAL-CED1Z. When I am trying to measure the noise floor with the EVAL-PulSAR-CED software, I am getting this (see attachments for zoom) spectrum:

  • AD7641 EVAL Board clipping and software issues

    Dear all,

    I have set up the EVAL-AD76XXEDZ with the AD7641 and the EVAL-CED1Z. When I am trying to measure a signal with the EVAL-PulSAR-CED software, I am getting this output:

    The signal parameters are:

  • 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?

  • RE: LTC2380-24 Multiplexing

    Hi Vitor,

    To deal with the bipolar signal, I would suggest using a fully differential amplifier such as the ADA4945-1. The amplifier can be used to translate the bipolar signal from your preamp to the signal level required by the ADC. Additionally the…
