• AD8332

    信号接入AD8332时会通过一个L1 120nH FB ,L1 120nH是表示电感的 而FB是表示磁珠的,我想问的是这个元件到底是电感还是磁珠?(附有原理图截图)

  • AD8332的放大问题

    AD8332其LNA在单端输入和差分输出时增益为19DB 其电压放大倍数是9倍 那么它的放大倍数能不能改变其它我想要的倍数 还是说只能是固定不变的

  • AD8332的最大可变增益放大倍数只有20dB

    我用AD8332做可变增益放大,采集超声信号,但是目前电路对信号发生器输出的3MHz正弦信号(10mV)实现的最大放大倍数为20dB左右,该增益是可以变化的,放大倍数在1~20dB范围内。

    但是实际上AD8332至少自带一个19dBLNA前置低噪声放大,目前我们电路最大才实现20dB的放大,看起来这个AD8332自带的LNA前置低噪声放大的19dB一点效果都没有,各位大神能否帮忙看一下电路原理图,谢谢!

    HP_O9和HP_O10是原始信号输入,OP_GAIN是增益信号的输入。

    测试电路时,增益信号由一个直流电源提供…

  • AD8333 - AD8332 interfacing

     

    Hi,

    I am developing a SDR receiver as my bachelor thesis. I am new in hardware design.

    This is expected block schema:

     

    I am using SDR concept, which is based on I/Q demodulator (AD8333) for mixing RF frequency to baseband.

    Then is signal…

  • AD8332 Amplifier, Is noise modeled?

    Hello,

    I am getting poor results trying to model noise when using the AD8332 in Orcad PSpice.  When looking at input referred noise with a shorted AC coupled input, I am seeing around a 200nV/rtHz noise floor (specs claim as low as .74nV/rtHz).  Can Analog…

  • AD8332 VGA Spice Model Gain Problem

    Hello,

    I am working with the AD8332 VGA spice model from Analog's website.  I know it says that all of the models are "AS-IS", but I am hoping to get someone smart with spice models to help me out.  It appears that the model does not correctly…

    Hope you are well. One AD8332 question need your help. Attached is the
    schematic.

    Below is several waves. The Gain of AD8332 is 40dB.

  • RE: Amplification and acquisition of ADG5419 output signal

    Hi Yangyulong,

    I would recommend using something like an AD8332, this part is commonly used in ultrasonic applications.  It has low front end noise and variable gain that can be adjusted with an analog voltage.  Take a look, to see if that matches up with…

  • AD8332_过载

    你好!有一个关于AD8332的问题需要您帮助。附件是原理图。

    下面是几个波形。AD8332的增益是40dB。

    波形C是AD8332 LNA的输入,它是一个1MHz负脉冲,幅度为-750mV;波形B是AD8332的输出。客户不清楚为什么AD8332的输出会失真。我认为-750mV幅度超过了AD8332的输入范围+-275mV。

    希望您能提供一些意见。

    Hi Doug,

    Thank you for your reply.
    I have already received your email and found the resources I need. I'm sure I will put it to good use. (ง •̀_•́)ง
