• ADA4860 LTspice behavior

    The ADA4860 spice model gives me unexpected behavior for the powerdown (PD) pin. For example, if I modify the model test fixture to set V- = -4V and V3 = -4V (PD pin) then the output is basically zero. This isn't blocking me (am actually interested in…

  • ADA4860 and Agilent ADS 2014.01 Compatibility Problem

    Hi everyone!

    I'm trying to simulate a circuit based on ADA4860 op amp in Agilent ADS 2014. I'm using official SPICE model downloaded from Analog Devices website (link: http://www.analog.com/en/products/amplifiers/operational-amplifiers/current…

  • RE: AD 9834生成正弦波问题咨询

    可以用于30MHz信号的产生, 只不过AD8014的带宽大一些避免信号的衰减

    如果发现信号质量不佳,可以更换更快的运放,比如ADA4860-1

  • RE: op-amp for high frequency

    Hi Lena,

    Are you using a single supply or dual supply? Dual supply would be a better option for this. You may want to use and consider the AD8099, ADA4860-1, AD8000 and AD8061 for your application. I think you want to design an Active Band Pass Filter…

  • RE: Opamps driving coaxial cables

    Hi Sergey,

    To drive a doubly-terminated 50 ohm coaxial cable, the driver op-amp needs to be able to suitably drive a 100 ohm load, and this is independent of the cable length it is driving.  It sees the same 100 ohm load whether it is driving 1 meter…

  • RE: .file_attr 1="1";

    Hi Gideon,

    Sorry for the delay in responding.

    The cause of the problem is "-file-attr CORE0" and "-DCORE0" both being included on the compiler command-line. Could you delete CORE0 from the "Additional attributes" in Tools Settings > CrossCore Blackfin…

  • ad7768-1

    Hello,

    I want to use the AD7768-1 with 5V AVDD1 = Vref and 3,3V VDDIO.
    In demo-circuits the AVDD2 is connected to probably noisy VDDIO!
    Wouldn't it be better to supply AVDD2 from 5V over a R-C-Filter, that would lower the voltage to around 3V?

    Additionally…

  • ADA4941-1

    Hi All,
    I am looking for OPAMP which can convert single ended signal to differential signal to drive the ADC which has differential input. I have selected ADA4941-1 and tested for -2 and +2 gain configurations which are mentioned in Figure 58 and Figure…
