• AD8132 Bandwidth test problem(AD8132带宽测试问题)

    最近测试AD8132带宽,原理图完全按照手册推荐电路设计,PCB为双面板。大信号Vout=2Vp-p下,G=1,实际测试带宽只有254MHz,手册推荐值是350MHz;G=2,手册值是190MHz,实际测试136MHz。不知道是哪里除了问题,请有经验的大神帮忙分析下,谢谢!

    Hello,

    The pin 7 has no internal connection or bond.

    Thanks and regards.

  • AD8132

    Hi,

    I want to interface the ADC and the radio.

    the problem is radio is having a common mode signal of 0.5V and ADC has a common mode signal of 0.9V.

    i need DC coupling between these ADC and radio. I sit a good idea to use AD8132 amplifier to switch…

  • AD8132 spice model

    Hi!!

    I have to simulate on OrCAD a front end with the AD8132, so I used the file ad8132.cir to get a spice model and then the part symbol; unfortunately that component worked in a very strange way in the circuit, so I realized a known circuit with the…

  • invalid behaviour AD8132

    We developed the schema which measures the current from shunt resistor (125uO).

    The first schema has ADC AD7687 and differential amplifier AD8132.

    But the voltage-code characteristic wasn't linear.

  • AD9235 with AD8132(AD8138)

     

    Hi

    Could you give me any advice as below?

    I have been designing PCB using AD9235 and AD8132.

    I have designed AD8132 using input signal impedance matching as 50ohms to get differential output.

    My question is to confirm the connection between…

  • AD8132 Vocm minimumum voltage.

    What is Vocm minimum Voltage allowed when powered from single 3.3V  for AD8132?  Differential Amplifier Calculator is set to minimum 1.4V.

    Multisim Component Evaluator doesn't complain going below 1.4V.  Acutally I am running at 1.25V.

    Can I use AD8132…
