• AD7862 & AD7863

    Hi,

    i have a circuit that requires the use of AD7862. however in my country (Malaysia) it is not available, and purchasing for outside of the country is time consuming and costly. i asked AD for a pin-compatible IC for replacement and they suggested…

  • AD7862-10 from VDD = 3.3 Vdc?

    Hello!

    I'm doing a project in which a voltage of 3.3 V is used to power the logic part, so the question is:

    Can I use a VDD = 3.3 V in a AD7862-10?

    Thanks!!! (Sorry for my bad English).

  • AD7862 conversion noise at sample rate

    I am diagnosing noise on a legacy design that has an AD7862 ADC.  Typical signal is 2 to 5 Hz sinusoid.  Sample rate is ca 7500 Hz.  Problem is that converted digital signal is affected by at least +/- 5% by the sample rate.  If I do an FFT I see the sinusoid…

  • Question for your timing chart of AD7862

    Dear Sir/Madam,

    Our customer have 3 questions for your AD7862 ADC.

    As for your time chart fig-1 following,

    Q-1
    During /CONVST=L, and
    When /CS=L and /RS=H, is your output data affected?
    I think that no problem for this case correct?
    But if /CS=L and …

  • AD7862在Linux嵌入式系统下如何实现最大采样率

    根据最新内核中的AD7949驱动程序只能实现单次数据采样,而使用触发器中断采样,将很大的消耗处理器资源,目前我们能够做到50ksps左右的采样速率,

    难道使用Linux系统无法达到最大250ksps的速率吗?我们查看数据手册发现,AD7862要求每次转换之前必须进行CNV使能,即SPI线CS必须拉高,这一限制导致采样率无法提高。如果这款芯片不行,能不能推荐一款4通道,采样率在200KSPS以上的ADC芯片。

    谢谢!!
