• AD8602 Offset voltage variation

    Hi,

    My customers are considering using the AD8602.
    So I got a question.

    They applied 2.0 V to the differential input pin and kept operating at 75 ° C for a long time.

    (experimenting with the circuit below.
    Connect a 6.8 kΩ resistor to GND and operate…

  • AD8602 Input & Output ABSOLUTE MAXIMUM RATINGS

    Hi,

    My customers are considering AD 8602.
    So I got a question.

    Is a protective diode etc. in the Input & output stage of the AD8602?
    If voltage is applied to Input when power supply is not being applied to the AD8602,

    I am concerned about whether the…

  • AD8602, Slew Rate data

    Hi,

    Regarding to Slew Rate data which is shown in datasheet, is 5.2V/us typical when Vs=3V, and 6V/us at Vs=5V. However we feel it may be slightly higher than these value. Could you please provide Slew Rate distribution data, like Figure 5. for Input…

  • AD8602: Difference between AR and DR suffix

    What is the difference between OpAmp AD8602 with AR and DRsuffix?

     

    R refers to R-8 package option (8 ld SOIC). A and D refer to the device
    electrical/temperature grade. Devices are sorted into different grades of the
    same device at final…
  • AD8602, D-Grade parts Offset Voltage Distribution.

    Hi,

    We can see Figure 5. and 6. Input Offset Voltage Distribution in AD8602 datasheet page.5. It seems these data is from A-Grade parts by looking at x-axes value. Could you provide equivalents of D-Grade parts ?

  • 求助:基于AD8602芯片的驱动电缆技术的实现

      以下是一个微小电容的测量电路,为了减小连接电容和电容测量电路的线缆引入的电容,采用了驱动电缆技术。其中用到了AD8602芯片,但没有给出具体连接图。哪位高手能给出一个连接图,另外放大器的性能对减小电缆电容很关键,能否推荐一个更好的AD芯片?

    上图中所描绘的元器件RLCLRGCG都是带有电容电阻的长导线电缆的等效示意图,只需要一个运算放大器OP作为射极跟随器就够了。作为射极跟随器(v=1,放大倍数为1的运算放大器,OP将导线电缆的内外电势保持一致,消除了信号电缆间的容抗,使信号导线与内屏蔽导线之间的电缆电容不起作用…

  • AD8602能做比较器用吗?它的输入级带钳位二极管吗

    手上有AD8602这个运放,想用作比较器,不知道是否存在隐患,另外它的内部输入级带有钳位二极管吗?

  • Understanding the datasheet

    Hi, I am having little trouble understanding the datasheet for AD8602.

    On page 3, table 1, Input Offset Voltage(AD8601/AD8602) is 80uV for 0<VCM<1.3V. But 3 lines below, it says VOS is 350uV for 0<VCM<3V.

    Does that mean Vos is typically…

  • RE: AD8602ARZ-REEL7

    Hello Kchan770, 

    There are no PCNs for AD8602 that documents a lead frame change. 

    I would recommend that you go back to your point of purchase to verify any concerns. 

    Thanks,
