• AD7357 fires back

    Dear colleagues

    we are using an AD7357 and an AD8132 to drive the inputs of the AD7357. Trouble is, we see large voltage swings at the Vin+ and Vin- of the AD7357 which are not related to the signal we feed into the AD8132. We use pretty much the recommended…

  • RE: AD7357 Serial Interface Timing

    Hi Terumasa,

          Let us make the latest datasheet as our reference which currently Rev E from the ADI website.

         I am assuming that you are referring to the power up times after partial power down of AD7357. The datasheet describes that when the conversion…

    Hi, Rahul.

    We use the AD7357 evaluation board with our Converter Evaluation and Development (CED) board. The CED board would provide all supplies and signals needed to operate the AD7357. You can also find the technical notes and software for control…

  • ad8138驱动AD7357,AD7357基准输出变为2.9V?

    采用AD8138驱动AD7357单端转差分,基准采用AD7357输出基准,原理图参考的AD7357参考设计,实际调试发现AD7357基准输出不正常,为2.9V,供电回路为正负5V,实测为4.9V和-4.7V。取下一片AD8138后对应回路的AD基准电压恢复正常,另外一路基准电压仍然是2.9V。请问是什么原因造成的。

    The data is the same for both generics.  The information I provided you for the AD7357 is the same for AD7928

  • RE: 大家好:在使用AD7357时,单通道输出不准确和采样频率提高后数据采样不准确

    1. AD7357芯片能够使用SPI的方式传输采集的数据.

    2. 请用示波器检查AD7357查分输入引脚上,VINA+, VINA−; VINB+, VINB−是否为正常的正弦波波形?

    3. 请用示波器同时抓AD7357数据接口/CS, SCLK, SDATAA, SDATAB的波形,检查时序是否正确?

  • AD7357的数据延迟问题

    您好!

    关于AD7357这款产品,文档中说AD7357的数据输出有一个采样周期的延迟。这个意思是说从第N次采样开始,到我能从AD7357得到第N次采样数据的时间间隔是一个采样周期?还是说从第N次采样结束,到我能从AD7357得到第N次采样数据的时间间隔是一个采样周期? 换句话说,像数据手册里Figure 30的图示,在采样的同时,实现数据的串行输出。那输出的数据是当前采样值还是上一个周期的采样值?

    谢谢!

  • AD7357 conversion time

    Hello,

    1) What is the maximum conversion time in the AD7357?

    2) Do I can sampling at 10 Hz?

    Thank you.
