• RE: code of the test pattern of   AD7960?

    Hi Maithil,

    I also want to verify my FPGA Design with the test patterns of ad7690, so could you please send me informations about the generated random code?

    Thanks

  • Digital Logic instead of a Microprocessor

    Is it possible to control a AD7690 in the 3-Wire CS Mode (Rev. C, Figure 34) by using the CNV and CNV and SDO  lines with only simple digital logic rather than using a microprocessor?

  • RE: AD7960 evaluation software使用问题

    您好,如果需要加入自己的算法,就不能使用评估板软件,评估软件不能提供程序扩展功能。

    Hi Sean, thanks. It seems you think you guys should have them, just forgot to put in the site. Will look forward to the quick response.

    Meanwhile, would you please take a look of the question raised in the link below. No answer for a long time.

  • RE: AD719x reference buffer amplifier?

    Jonathan,

    the 7uA average current is not a problem for most amplifiers, but the transient current is, as I explained above.

    Therefore "low output impedance at lower frequencies" is not relevant, but tolerance to transient loads is.

    You mention…

  • RE: CN0335 - data aquisition PMOD

    Hi Saurabh,

    The CN0335 comes ready to use out of the box with a +/-10 full scale input range.  The attenuation network (resistors, capacitors, and amplifier) ensures the voltage seen by the ADC is not outside its full scale range. (which is only 2.5V…

  • RE: ICP Piezo Force Sensor Interface to microcontroller

    Greg,

    I am considering mid-reference to be the middle of the ADC's reference. In other words, if you supply your ADC with 5V reference, then it would be 2.5V. You will want to drive the reference pin this way because your signal will be bipolar, and…

  • SAR型ADC前端RC滤波器设计问题

    笔者最近在做一个多通道数据采集项目,涉及到数个通道的高速切换。

    根据传感器输出信号的交直流特征和要实现的吞吐量,选择了ADI公司的18-bit SAR型模数转换器AD7690。

    确定了ADC后,笔者进一步设计了ADC前端的放大电路和RC滤波电路,悲剧也就从此开始。

    笔者遇到一个两难的问题,如上图所示,为确保系统对阶跃信号有很好的响应

    (本质是为解决ADC输入从负满量程跳到正满量程时如何迅速、准确建立的问题)

    应使RC滤波电路的-3dB带宽尽可能地宽,缩短反向建立时间,使ADC在tA…
