• RE: AD8334 Frequency Responce

    Hi Kutay,

    Since this device is designed to be powered from a unipolar source, the input stage has a bias system and the voltage at the bases should be within 0-5 volts. This uses capacitive coupling between the signal source and the input. The value…

  • One question from AD8334.


    Dear Sir:

    I  want to layout AD8334 on my PCB and I have one question from AD8334 as below picture.
    Pin 3,14,21,32,40,60 are NC pin ; but , The reference circuit in datasheet page
    49 only pin 3,14,21,60 connect to GND and Pin 32,40 floating . I aslo can…

  • RE: ad8334 cascading issue

    Hello wouter.devriese,

    Would you mind sharing the AD8334 portion of your schematic so I can see all of the connections?  If possible, can you label the supplies, where you are applying the input, and where you are measuring the output?

    If the large mechanical…

  • Using the AD8334 Evaluation Board

    I'm having a problem using the AD8334. I'm using the board as is to make sure it works per the datasheet. Here is what my problem is:

    I only measure the 2.5VDC bias; my input sine wave 25MHz signal that is 10mVpk-pk, comes from an Agilent signal…

  • 关于AD9252前端匹配放大电路的选择

    板卡选择ad9252芯片进行16路AD转换,采样频率可能会低至零频或是较低频率,芯片手册中推荐的功放电路为AD8334。

    但是在之前的板卡中AD8334在接近零频或低频中的工作状态不正常,请问AD8334是否有这方面的问题,如果是的话有没有适合的功放芯片推荐用以匹配AD9252(共16路AD)。

  • Unexpected Gain with AD8334 on AD9252-50EBZ eval board

    Hello everyone, I have an AD9252-50EBZ evaluation board. The board contains two AD8334 VHF VGAs that can optionally be placed into the front-end signal path into the AD9252 ADC by changing some resistor values on the board. I've followed the directions…
