  • 采样保持芯片AD783的使用

    您好!

           有俩个问题请教!附件里是AD783的Datasheet里推荐的一个采样电路。

    我的问题是:1.这个电路里的ONE-SHOT 是什么电路,

                          2.那个触发器使用的是什么型号的触发器呢?

            谢谢了!

  • 关于采样保持芯片的选型问题

    各位大牛好

           我想选择一款采样保持芯片来实现对脉宽1ns的周期脉冲信号进行等效采样,后端ADC的采样频率为10MSPS。

    1)AD783的Acquisition time典型值是250ns,是不是只能使用小于4MSPS的ADC采样场合。如果不是,我的需求是否可以满足。

    2)如果我要实现1ns内等效采样10个点,对于参数Acquisition time是否精度必须小于100ps,还是只要系统提供的触发脉冲边沿精度满足小于100ps即可。

    3)如果AD783精度不够,HMC760是否合适,是否还有更低成本的解决方案…

  • RE: AD7928 Track-and-Hold Acquisition Time

    Hi,

    The AD7928 has an integrated track and hold and should not need the AD783.

  • RE: High-speed infinite sample and hold

    Hi Sean,

    Thank you very much for your help. Unfortunately, we can't use sample and hold amplifier such as AD783/781 because they cannot hold the Vout forever. I wonder can we make a circuit like the attached one above. At first, the switch is on and…

  • ADALM1000 MHz Sampling Oscilloscope / Spectrum Analyzer completed

    I have now completed the design and construction of both PCBs that make up a high speed sampling front end plugin for the ADALM1000. The programmable DDS sampling clock generator board was discussed here.

  • RE: 峰值保持电路 运放推荐

    AD783满功率带宽2MHz,可能满足不了你的需求,可以考虑跨导放大器+二极管+电容的方案

  • High Speed SHA turns the ADALM1000 into MHz Sampling Oscilloscope / Spectrum Analyzer

    I’ve been working with the ADALM1000 for a few months now and I thought it might be a good time to dust off this idea I wrote about in the November 2011 issue of Analog Dialogue and see how well it works with the ALM1000.

  • RE: 峰值保持电路

    您好,PKD01已经停产了。单通道的峰值保持器您可以考虑AD585,AD781,AD783这几款。所有峰值保持器的列表请见该链接:http://www.analog.com/en/specialty-amplifiers/sampletrack-and-hold-amplifiers/products/index.html

  • RE: AD783JRZ

    Hi Adam,

    Are you looking for a SPICE model to simulate the performance of the part? Unfortunately, the AD783 is one of our older parts and we do not have a SPICE model available for it.

    Apologies for this inconvenience.
