• The driver circuit of AD9633 or AD9681

    Hi Guys,

    We are using many AD9218 chips, and the driver using AD8138, which is ideally suited for broadband dc-coupled applications. The AD9218 datasheet also gives the reference circuit by using AD813x devcies.

    I read the datasheet of AD9633 and AD9681…

  • AD9633使用问题咨询

    AD9633手册里提出由于噪声因素,大部分放大器不适合作为其驱动器,所以推荐了使用双巴伦及变压器方案,我的问题是变压器方案属于AC耦合还是DC耦合啊?

    AD9681也有类似的问题,而我之前使用的AD9218手册里就明确推荐了使用AD8138作为驱动的示意图,且DC耦合。现在问题是一方面,我需要使用更高集成度的ADC,另一方面,我又要求对信号输入到ADC进行DC耦合,怎么办?

  • AD9633/HSC-ADC-EVALCZ Visual Analog comparison to Oscope not matching

    I'm comparing data captured by the oscope and by the ad9633/evalcz combo using Visual Analog default data capture and I'm not understanding the difference.

    It doesn't quite look like it's reversed, and it's supposed…

  • Questions: When ADA4930 driving AD9633

    1. The input common-mode voltage range of ADA4930-2 should be 0.3~2.8V. But, i found this parameter has different range in Chinese version datasheet, where is 0.3~1.2V. Also, there is same issue about output voltage range.

    2. There are two blocks between…

  • 关于AD9633的设计

    第一次使用这种类型的ADC,希望ADI公司的技术工程师能帮帮忙。

    目前在设计阶段,遇到以下问题:

    1、数据手册中提到了SYNC引脚,但是该引脚的具体使用方法未明确说明,现在我只使用一片AD9633,请问该SYNC引脚怎么控制?其同步的是什么信号?

    2、当AD9633使用外部参考电压源时,要对VCM引脚处理?

  • AD9633 Measurement

    Hi all,

     

    We bought an AD9633 80MSPS and make a PCB to do the measurement.

    But we find out there are some codes will go wrong on some regular voltage with the 80MHz CLK.

     

     

    (no error In 20 MHz or 40MHz CLK)

    (We didn't use the SPI to change any default…

  • AD9633 Over Range Behavior

    Does the AD9633 have any indication of an Over Range / Clip condition?  The behavior that I am seeing is that the ADC code seems to wrap back to zero (using Offset Binary).
