• can AD8513 be used as a instrumentation amplifier?

    In AD8513 data sheet mentioned that it can be used as a instrumentation amplifier. can anyone please confirm it

  • what is the input impedance of AD8513?

    Hi all,

    i go through the data sheet i dint get the input impedance of AD8513  .. anyone can please suggest me to how to get it?

  • AD8513功耗問題

    Hi,

    我採用AD8513 14pin封裝

    以電源供應器兩個channel串聯供電

    V+為+12V, V-為-12V


    上電後, 兩個channel都是8mA

    回頭看了datasheet寫到~~

    POWER SUPPLY

    Supply Current/Amplifier (ISY)

    AD8513      2.75mA

    這是為什麼差這麼多阿? (線路只插了V+及V-, 其餘浮接)

    請先進們指導, 謝謝

  • 关于AD8513滤波电路的问题

    我是使用AD8513来做的带通滤波电路,中心频率1KHZ,增益为0dB,第一版使用了SOIC14封装的片子,测试结果OK。第二版更换为TSSOP14封装的AD8513,增益始终达不到0dB,而且出现了增益不稳定的现象,就是多次测试的结果都不一样。问题应该出在哪里?我更换了不同批次的TSSOP14的片子也不行,电路的走线或者布局有没有可能有影响?!

  • RE: Can the AD8513 be powered by a single 5 V supply?

    Hi Leo,

    Yes, you can use the AD8513 in single supply but 5V is not advisable due to IVR. I would suggest you to use 10V supply for your application.

  • AD8513 Wide Bandwidth and Phase Reversal

    Hello!

    I am analyzing stability of a number of circuits using AD8513, my first approach is through PSpice simulation and rate-of-closure criteria. So first, I need to confirm the model of this opamp behaves as it is depicted in its datasheet. In Figure…

  • RE: OP4177 opamp is not working as voltage limiter.

    Ruchi,

    I think you might be stuck.  The precsion bipolar op amps usually have diodes between the inputs to protect the diff pair so you don't zener the EB junction.  You might look at some of the JFET op amps, such as the ADA4000-4 or the AD8513, but…

  • RE: dual-supply opamp's power up sequence

    Hi Aoki,

    According to one of our Product managers, there is no power up sequence required for the AD8513. But if you want a good way to turn on the device, you may apply the V- first before the V+.

    I hope this helps!

    Best regards,

  • RE: quad opamp, isolation amplifier

    What are your supply rails? The LM747 will tolerate 22V supplies, which is more than most opamps will take.

    The AD8513, AD8674 and OP470 may be worth a look as they all have better performance. I don't know about Mil spec though.

  • Die structure in OpAmps

    I would like to know what is the difference in the die structures of the following Op Amps

    • AD8620
    • AD8512
    • AD8513
    • OPA4227

    The main reason to know more about the die structures is to know how much the IC's will dissipate power supply current…
