• Using AD7680 for ultra low sampling rate

    Hello,

    The requirement for one of the projects is to operate a ADC in less than 1kSPS down to 10SPS.

    Can AD7680 be used for these low sampling rates?

    If not, is there such an ADC that can be operated to almost DC levels?

    If yes, how the serial data will…

  • AD7680 10uF Tantal vs. 10uF Ceramic capacitor

    Hello,

    I have an question concerning the 10uF capacitor which is required on VDD. In datasheet an tantal capacitor is

    recommended. Would there also ceramic work? What would happen if I use an ceramic capacitor?

    Best regards

  • AD7680 Voltage Level SDATA

    Hi,

    I use AD7680 in an application with an host microcontroller running on 1,8V which also is communication voltage on microcontroller.

    AD7680 is running with 3.0V. Does this cause trouble because in the datasheet stands for logic Input:

    Does this mean…

  • AD7680无输出的疑问

    我在电路中使用AD7680检测一个电压值,大楖5秒检测一次,使用CPLD对AD7680进行控制,现在AD7680芯片的SCLK设置为1MHZ,AD7680的数据输出管脚一直为低电平,没找到原因,请问有谁遇到过相同的问题。

  • AD7680 non-monotonic clock operation

    Hi

    I would like to control the capture timing of input signal and sending timing of converted data.

    When CSb goes LOW, then VIN signal will capture.

    After that, the clock stop for a while, about 100uSec, and put clock again.

    It looks like clock stretch…

  • Sigma-Delta ADC with equivalent specs to the AD7680 SAR ADC...

    Hello,

    I have a medical customer here in town that has been looking at the AD7680 SAR ADC for about a week now (meets most of their requirements).

    However, they just recently came to me and asked if a Sigma-Delta architecture is a better fit for their…

  • ADI的ADC通过SPI读取转换结果时一次只能读取一个转换结果,而不能连续读取吗?

    我选了几款带SPI接口的ADC(如AD7680,AD7982等),看SPI时序时,发现在CS/CNV拉低时,一次只能读取一个转换结果,而不能连续读取,要读取下一个时必须得再次拉低CS/CNV。

    请问有哪些型号是支持在CS/CNV拉低时可以连续读取转换结果的?谢谢!
