• Questions about AD8512 at a single power supply

    Hello,

    My customer is considering to use AD8512 at a single power supply, so they need to know additional specifications of AD8512.

    Please refer their questions and let me know your answers.

    Q1) Would you let me know the Max. supply voltage of AD8512…

  • Oscillation and heating on AD8512 used as Sallen Key low pass filter (Gain=1)

    Issue is that AD8512 Opamps in Sallen key low pass filters (having G=1) oscillate with nearly 8V swing and high heating of two AD8512 ICs in two boards.

    This board works on external 24V, and most experiments that have been done & explained below have…

  • 请教测高阻器件电压AD8512

    工程师们，你们好！我想做的是一个测量高阻器件上电压的电路，测量DC电压，器件阻抗大约是在几百兆。第一步做的是跟随，用的是JFET高输入阻抗的AD8512. 电路如图。但是问题是当正向输入端接上这个100M的电阻时，会降低输入阻抗，这个无法接受。不接这个100M电阻的时候，由于没有给正向输入端提供偏置电流，输出值会锁在一个较大的电压值上，这个输出也无法接受。有没有一种办法，可以使不接测试器件时，使输出接近于0，接上测试器件时，输出就是器件的输出？我知道这不是运放的问题，请ADI的工程师们不吝赐教，谢谢…

  • AD8512ARM supply pin floating

    Would you let me know what is the impact on -15V supply pin of AD8512 is floating? Is it electrically stress the IC?

  • Antilog Amplifier with SSM2212

    In the datasheet of the SSM2212 you show a fast logarithmic amplifier using the AD8512 and some specific resistors for temperature compensation (an amazing detail!). For an interface to one of my RF circuits, I need an antilog amplifier. Could you suggest…

  • AD822: Phase reversal

    Q 

    Tha datasheet states that the opamp AD822 do not phase invert the output signal
    when the input signal exceeds the supply voltage, but it does. How can that be?

     

    A 

    It is important to distinguish between over-voltage protection (i.e. the

  • AD8512_Stability Analysis Multiple OPAMP_CIRCUIT_LTSPICE

    Dear Team,

    I am trying to find the phase margin of one of my circuits which contain two opamps(AD8512) and one instrumentation amplifier(AD8421).

    I break the FB loop in the first opamp(U1, please see the figure). I am getting a phase margin of 10.

    Could…
