• LT6656:Voltage Variation while doing ADC Measurement

    Hi ADI Team,

    We are using LT6656 to generate a reference voltage. At some instance we do want to measure it. Our assumption is that the voltage shall dip when we try to measure as this is given direcly to the ADC.

    Our requirement is as follows:-

  • RE: LT6656-2.5时怎么使用LT6004升高基准电压的,一直没看明白

    LT6656-2.5是个REF,LT6004是个OPA,运放的虚短虚断,右侧同向放大,生成2.75V;左侧OPA+BJT构成恒流源,依旧虚断虚断来分析,流回OPA的电流很小,2N5086的E极电流= (2.75-2.5)/249K ,而输出电流是BJT的Ic,两者有函数关系。。

    具体的可以用LTSpice仿真一下的。

  • RE: SPICE Model for AD8610 does not work

    Hi Fabian,

    I tried to emulate your circuit and I noticed that the voltage reference LT6656-5 is affecting the LTspice simulation with AD8610 causing slow convergence or at times non-convergence and incorrect output voltage. Even if you change V2 and…

  • 微功率电压基准输入输出关系

    【线性产品->基准电压源->微功率电压基准】

    微功率基准电压芯片比如LT6656-5,若VIN低于手册推荐电压值时(5v+),Vout输出为多少?假设:VIN=1v,输出电压为0v还是约1v呢?

  • RE: ADA4084 SPICE Model

    Please find screenshot of my schematic attached. I think perhaps you used AD829A model instead of AD829, which doesn't seem to produce correct results. V(hg_out) should be gain ~30dB higher than V(lg_out). 

    I've got the AD829 / ADA4084 simulated fine…

  • Wireless Current Sense

    Continuing with our series, Combo Circuits from the Lab, join Kris Lokere as he tells us what exactly makes Wireless Current Sense.

    Measuring the current that flows through a sense resistor seems easy. Amplify the voltage, read it with an ADC, and…

  • 工程师博客分享——从信号链、电源管理到无线组网,真正的无线电流检测电路是这样的

    上期的参考电路,大家表示很感兴趣→——采用ADI/LTC产品组合的超高精度可编程电压源

    那就继续我们的“组合参考电路”系列,今天的电路将告诉我们如何进行无线电流检测。

    测量流经检测电阻的电流似乎很简单。放大电压,用ADC读取,不就知道电流是多少吗;但如果检测电阻本身的电压与系统地电压相差很远,检测就会变得比较困难。典型解决方案是在模拟域或数字域消弭该电压差。但这里介绍一种不同的方法——无线。

    模拟电流检测IC是紧凑型解决方案,但其可承受的电压差受限于半导体工艺。很难找到额定电压超过100V的器件…
