  • AD8334 Frequency Responce

    Hello,

    I want to use AD8334 but curve of gain and frequency response ( figure-2 ) starts at 100Khz in AD8331/AD8332/AD8334 datasheet.

    Why starts at 100Khz? Can I use it under 100Khz?

    My project center frequency is 75Khz (under 100Khz).  My project includes…

  • ad8334 cascading issue

    Hi all

    I'm building a circuit to detect the envelope of a very small signal (some 10s of uV @250kHz, an ultrasound echo. I calculated that I'd need approx 90dB of gain before sending it to a leaky peak detector (and then to ADC: ltc2334-16).

  • 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…

  • 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…

  • AD8334 - Consequences of Exceeding the Input Voltage

         Good afternoon.  I have an A&D customer that is looking to replace the TI VCA2615.  One of the parts under consideration is the AD8334.  On page 25 of the data sheet, it states that "... the maximum input signal before saturation is ±275 mV or…

  • 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…

  • A couple of questions for external device values of AD8334

    Dear Sir/Madam,

    I have a couple of questions for you.

    As for your external devices AD8334 datahseet 84.5ohm on Fig-85 page-32 ,and 187ohm, 374ohm on Fig-86 page-32,
    how can I calculate and bring these values?

    Otherwise how did you fix these values?

  • 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)。
