• RE: AD7466 VIN drops issue

    Hi Jonathan,

    The AD8512 and the AD8620 are not pin-to-pin compatible with LTC2055 so I would not like to use them.

    I'll try to test with AD823A.

    Regards,

  • Is offset of power supply voltage possible?

    Hi all,

    I have planned the product using AD8512ARMZ.

    Although operation Voltage of AD8512 is ±15 V, we want to use by V+=+24 and V-=-5V.

    And 0V-20V are required for the output voltage range.

    It is used where all of power supply voltage, input voltage…

  • RE: 请问这个滤波电路设计是否合理?运放工作的状态是怎样的?

    您好,您使用的运放芯片不是ADI的产品。请到相关的技术支持进行咨询。

    另外,如果您需要该芯片的替代芯片,可以考虑AD712,AD8512.

  • 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…

  • 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…

  • RE: Die structure in OpAmps

    Hi Abhijit Pethkar,

    Thank you for clarifying that. I understand that the products you mentioned seem to function similarly. After all, these amps are generally classified together under precision category, especially that AD8512 and AD8513 belong to…

  • RE: ADA4627-1 and capacitive loads

    Hi Steffen,

    In line with my recommended parts in my first reply, I found out that the newer ADA4610-2 (dual) could be a much better replacement. It is the direct next generation of AD8512 (dual version of AD8510) and at the same time better trimmed version…

  • AD9629 in single ended mode. input minus vref.

    Hello,

    I ve got a question regarding the high speed AD9629 for a new design, in single ended mode. I need to know if my solution is correct. In single ended mode such as figure 39 of the datasheet. Can I use VREF to substract my input and shift down…

  • 工程师被辞职开始怀疑人生?可能是假芯片在捣鬼

    近日在与非网看到这个帖子,ADI专家怎么看冒牌芯片问题?很少非正规渠道买片子,大家怎么看这个问题??

    帖子是这样讲的,说某朋友爆料了这么一件事,他们在一款小信号的采集板设计中,其前端的模拟信号处电路上,采用了多片运算放大器AD8512ARMZ,批量阶段,在某贸易商处买了好几百片,当板子全部做好后,怎么调试都会工作不太正常,总有干扰的问题出现,因为本来是属于小信号电路,一开始一直在设计上找原因,问题始终解决不了,都要崩溃了。

    重点来了,他们脑筋一闪,找了一家可以做芯片拆解公司,把这批次芯片和之前正规渠道的样品同时decap后对比…
